I've been doing front-end development since the early 2000s. Starting initially with just HTML and CSS, I progressed to using various languages and libraries to help with templating, and CSS preprocessors like Less, Stylus, and Sass/SCSS. I am fluent in various CSS frameworks/libraries like Bootstrap, Material UI, Foundation, and Tailwind, and now that front-ends are primarily single-page apps, I have worked extensively with CSS-in-JS tools like styled-components, emotion, radix-ui, shadcn.
I have also done an extensive amount of front-end development for server-rendered apps like WordPress, Drupal, CakePHP, custom PHP apps, Handlebars and other moustache-inspired templating engines, server-rendered Rails templates, and similar technologies in other languages like Go and Rust.
I do Responsive Web Design, which means I develop responsive interfaces for websites and web applications that are not only compatible with, but also optimized for all screen sizes and devices. I build web products to support the user's preferred appearance mode, including light mode and dark mode. My expertise in CSS allows me to help teams migrate their existing, large front-end codebases to support dark mode or be responsive and support mobile phones.
I use a variety of JavaScript libraries and frameworks to build interactive web front-ends including JavaScript, React, Vue, Svelte, Ember, AngularJS, and jQuery.&nbsp;
I work with designers with varying levels of expertise&mdash;from your most opinionated senior designers to your more junior designers that could benefit from guidance from a tech lead to help them make their designs more efficient to implement to save time during development and increase team velocity. I use Figma and Sketch as a developer to help me ensure my implementations are accurate as I strive for pixel perfection.
For more bootstrapped teams without designers, I design in the browser by implementing the desired functionality and making design choices as I go, leveraging the team's existing design system, brand guidelines, and UI frameworks. I can also use Figma to make wireframes or basic designs for stakeholders who want to see something before it's implemented.
As a front-end tech lead, I have led multiple projects to build component libraries to help teams build UI faster. My experience helps me understand the importance of separating behaviour from style so that our team can move faster. I also structure my web apps and teams in a way to allow team members with a diverse set of talents to thrive at what they do best, for example, allowing those who prefer CSS and UI development to focus on that, and those who prefer working on behaviour and business logic to focus on that.
I can augment your existing team to provide that front-end development expertise and guidance your team may be lacking, or work alongside your team of experts the way they prefer to work to help them power through a big project.

Mobile Development

As a tech lead, I like to set my team up for success by setting up a solid codebase and all the automated processes the team needs from the start so they can focus on building.
I meet with stakeholders to gather a thorough understanding of the stakeholders' goals and priorities, which helps influence which technologies to choose.
After choosing appropriate technologies for the job, I set up the codebases with CI/CD pipelines for testing and deployments, as well as linting and other automated tasks. This allows me and my team to focus on building rather than chore-related tasks.
To support my team I like to write extensive documentation that is easy to follow including style guides and the occasional instructional tutorial when appropriate. I like to provide style guides for all languages used, code examples, and design systems to support developers of all experience levels. I also make myself available to team members for mentorship including doing pair programming with peers and juniors, and running workshops to grow the team.
I like to communicate transparently and frequently in Slack, documentation, and meetings so that stakeholders are never left in the dark with regards to status on a project.
When it comes to building teams, I try to source as fairly as possible and include applications from developers from both traditional and non-traditional backgrounds, as well as use structure assessment practices to fairly assess candidates abilities rather than go by gut feeling which can lead to bias in the interview process.
I prioritize building the right organization framework and processes up front to create a supportive, healthy environment so teams can do their best work. My primary goals are to increase productivity so that team members feel empowered to contribute code and opinions, have a sense of ownership, and are motivated to ship quickly, and avoid scenarios that can introduce conflict and leave engineers feeling unmotivated.
When building teams, I put a strong emphasis on Diversity, Equity and Inclusion, and prefer working with companies with the same values, or at least those that demonstrate that they're willing to grow in that area.
If this sounds like a good fit for your engineering organization and you think you may like to work with me, please feel free to <a href="https://tinaciousdesign.com/contact">contact me</a>.

As a technical leader, I aim to set up full-stack web and mobile software development teams for success.
I believe the right tools and automated processes in place, a healthy risk-free environment where devs can communicate and disagree, transparent communication, documentation, and a diverse group of individuals on the team to get a diverse set of opinions and influences all help build successful teams.

Technical Leadership

As a full stack web and mobile developer, I have been designing and developing software for web and mobile since the early and mid 2010s.
I design systems based on your team's short-term and long-term goals.
I work with new companies on a limited budget to design software to help them get to market as soon as possible.&nbsp;
I work with mature companies to help them redesign and rewrite their existing software, and help them solve problems where their current solution falls short, as well as migrate from expensive technologies that made sense to choose at the start but don't scale financially with the current load on their systems.
Back-end programming languages, web technologies, single page apps or server-rendered apps, micro-services or monoliths, serverless or servers, SQL or no-SQL, native desktop or mobile apps or cross-platform solutions&mdash;there are many decisions to make when it comes to the system design of a product. There is no single right answer, and no silver bullet programming language or framework. I help you design a system based on your unique situation, what's important to you, and your priorities and goals.
I can augment your existing team to provide that&nbsp;system design expertise&nbsp;and guidance your team may be lacking, or work alongside your team of experts the way they prefer to work to help them power through a big project. I'm a full stack web and mobile developer based in Canada, and I work with teams locally and internationally to help them write software. If you'd like to work together, feel free to <a href="https://tinaciousdesign.com/contact">contact me</a>.

How a software system is designed will have an impact on how well it can be maintained and built on, and how fast your team can ship. Let me help you build a solid foundation for your software.
Maybe you've asked yourself: Which back-end language or framework should I use? Should I do native apps or go cross-platform? Should I use an expensive off-the-shelf product or build my own? What kind of database should I use?&nbsp;
If you&rsquo;re looking to develop a product, I&rsquo;m here to help you make the right technical decisions for you from start to finish.

Software System Design

I build websites and apps that users can manage themselves.
I enable my clients to manage the content on the websites and mobile apps I build them by leveraging open-source content management systems like Strapi, WordPress, Drupal, and ProcessWire.
I also work with cloud-based and headless content management systems like Dato CMS, Contentful, Airtable, and Strapi, among others, as well as no-code and low-code platforms like Retool.
I have been building with content management systems since the early 2000s and use CMS technologies to manage the content of my own websites. All of the content on this website is managed by a content management system.
I also build custom plugins to enhance functionality when the existing plugin ecosystem doesn't have something that can solve the problem.
A content management system solution might make sense for you in the following cases:
<ul>
 <li>You are a graphic designer or artist and would like a custom-built website to showcase your work</li>
 <li>You are a restaurant owner and would like a website that you can update yourself when you need to change the menus, hours of operation, contact information, image gallery, or other information on the site to showcase your restaurant</li>
 <li>You have a decent amount of structured data that you'd like to display for web or mobile</li>
 <li>You want to manage a variety of content and serve it as a REST API for your web and mobile apps to consume</li>
 <li>You need non-developers at your company to be able to create, update, and manage content on your website without relying on your dev team</li>
 <li>You want to build tools to help you run your business, e.g. accounting or invoicing software, etc.</li>
</ul>
I can augment your existing team to provide that&nbsp;content management system expertise&nbsp;and guidance your team may be lacking, or work alongside your team of experts the way they prefer to work to help them power through a big project. I'm a full stack web and mobile developer based in Canada, and I work with teams locally and internationally.

ProcessWire is a great, light-weight, easy-to-use PHP-based content management system. It's lesser known than Drupal and WordPress and definitely doesn't get the recognition it deserves, but it's a great alternative to these technologies. In my opinion, it's easier to use than both, and offers more flexibility than WordPress for custom content types, and is generally much simpler to theme for compared to Drupal. ProcessWire is quite mature, having been around for almost 2 decades, and is a great choice for my clients who want to update the content on their website.

ProcessWire

Drupal is a PHP-based content management system that is often leveraged for larger content sites. I have expertise in Drupal theme development.

WordPress is a powerful blogging engine that can also be used as a content management system for server-rendered apps, as well as a headless CMS for more modern front-ends like staticallyl generated websites (SSG) with technologies like Next.js and Vue.js.

WordPress

Strapi is a Node.js-based headless content management system. It has a slick admin dashboard that is quick and enjoyable to use as a content creator.
Strapi has a well-documented plugin development API, making it easier for developers to inject UI elements into the default CMS to extend functionality, for example, generating PDF's from content.
I use Strapi to build content-focused websites and internal tools, including my own invoice management software.
One of the benefits to Strapi over more traditional PHP-based content management systems is that it can be hosted on ephemeral infrastructure-as-a-service platforms.

Strapi

Sometimes it makes sense to use a low-code/no-code platform to build internal tools. These can be cloud-based or self-hosted.
Low-code tools help you save development time and are great for a variety of tasks:
<ul>
 <li>analytics dashboards</li>
 <li>performing content moderation for user-generated content</li>
 <li>helping your users manage their accounts</li>
 <li>other important tasks where you need a real human involved</li>
</ul>
Low-code tools I primarily work with include Metabase and Retool, but I'd be happy to help out if your team has a different preferred option.

Content Management

Since the early 2010s I've been developing websites with a focus on accessibility. Early in my careeer, I worked on projects for not-for-profits that were government funded, and one of the requirements of receiving the funding was to ensure that the websites passed the strict accessibility requirements set out by the provincial and federal governments, which at the time meant that it needed to meet the Web Content Accessibility Guidelines (WCAG 2.0) for AAA compliance, the Accessibility for Ontarians with Disabilities Act (AODA), and had to be compatible with Internet Explorer 6.
There are various ways to support accessibility, including graceful degradation and progressive enhancement, as well as providing alternative more accessible formats for content.
While <a href="https://tinaciousdesign.com/portfolio/tangerine-bank-redesign" target="_blank" rel="noopener">financial service</a> and <a href="https://tinaciousdesign.com/portfolio/sheridan-college-redesign" target="_blank" rel="noopener">higher-education</a> companies have stricter accessibility requirements, caring about accessibility can help all companies make their software easier to use and their content easier to consume.
If your business has a requirement to conform to strict accessibility standards, or you just want to make your software and content accessible to as many people as possible, I can help with that. I can augment your existing team to provide that accessibility expertise and guidance your team may be lacking, or work alongside your team of experts the way they prefer to work to help them power through a big project.

I make websites and mobile apps for people regardless of technology and ability, and can create accessible, enjoyable digital experiences for users of all abilities.
I can provide accessibility consulting and development as per the Web Content Accessibility Guidelines and other guidelines.
Early in my career I worked on projects with strict accessibility requirements, and since then accessibility has always been top of mind for me.

A local tattoo shop in Canada hired me as their Tech Lead and primary developer for a new mobile app project. The app is geared towards tattoo artists and other body modification service providers (piercers, brow artists, scalp micro-pigmentation artists, etc.) The goal of the app is to help service providers and clients find each other. The app was designed by their in-house designer and my role was technical leadership and&nbsp;full stack development&nbsp;on the backend, the website, and&nbsp;Android.
Features of the Android app include:
<ul>
 <li>Ability for service providers to&nbsp;post a service listing&nbsp;(opening). This functionality is similar to Kijiji or Craigslist but for tattoo artists and other body modification service providers</li>
 <li>Allows service providers to create&nbsp;posts with multiple images. This functionality is similar to Instagram.</li>
 <li>Ability for clients to&nbsp;find artists by service and location&nbsp;on the Find tab. Clients can provide their location or choose from suggested locations to find service providers near them or in a supported city</li>
 <li>Ability for clients to follow artists via the &ldquo;VIP&rdquo; feature.</li>
 <li>Ability for artists to&nbsp;send broadcast announcement messages&nbsp;to all of their followers. This feature was a rewrite of a feature that another developer took several months to deliver but hadn&rsquo;t quite worked as desired. At the time of writing this post, it is not live yet.</li>
 <li>Full stack features to support an&nbsp;invite-only artist onboarding flow, allowing service providers to only be allowed to sign up if they receive a one-time use link by another service provider on the platform. This exclusivity feature was specifically requested by the client to limit access to the app.</li>
 <li>Push notification configuration&nbsp;allows Android users to customize which notification categories they&rsquo;d like to receive notifications for, if any.</li>
 <li>Allow users to customize their profiles including profile image, name, username, profile details, and pronouns</li>
 <li>Notification feed&nbsp;for clients and artists to stay in the loop with activity in the app (broadcasts, new posts, listings, etc.)</li>
</ul>
Technical features:
<ul>
 <li>Location-aware search queries&nbsp;to allow resources to be indexed by location and queried based on distance from a provided location, e.g. 50 km away. This allows users to choose a city and find service providers within a specific range of that city.</li>
 <li>Deep linking&nbsp;functionality on Android (verified app links) and iOS (universal links). This was implemented to support linking into posts, listings, and to support the exclusive invite-only artist onboarding flow.</li>
 <li>Push notifications&nbsp;functionality to alert artists when they have a new follower, as well as to alert followers when an artist they follow has created a new post, a new listing, or sends a broadcast message.</li>
 <li>Google Maps Platform&nbsp;implementation to support auto-complete lookup and rendering of maps</li>
</ul>
As the Technical Lead of the project, I owned the development of and was the&nbsp;primary contributor on the backend API&rsquo;s,&nbsp;native Android&nbsp;app,&nbsp;website, and oversaw the development of the iOS app. I led a team of approximately 2-3 developers. I worked with the client to architect the solutions from a full stack perspective to find the best solution from a wide angle.
<ul>
 <li>System Design&nbsp;from a full stack perspective.</li>
 <li>Implemented&nbsp;CI/CD workflows&nbsp;(Continuous Integration, Continuous Deployment) to support automated testing and deployment for both the Android app, the backend services, and the website
 <ul>
 <li>Automated deployments for the backend services and website</li>
 <li>Automated deployments to Firebase App Distribution on Android</li>
 <li>Semi-automated deployments to the Google Play Store including automated code signing</li>
 </ul>
 </li>
 <li>Documentation and best practices: As the Tech Lead, I wrote best practices docs to support the other developers on the team. Documentation includes both manually- and technically-generated diagrams to help onboard developers.</li>
 <li>I created&nbsp;code generation&nbsp;tooling to remove the need to write boilerplate, and encourage consistent patterns.</li>
 <li>Overseeing the implementation of the iOS rewrite in Swift UI</li>
 <li>Service&nbsp;uptime monitoring&nbsp;to ensure production apps stay up and the team could respond to incidents</li>
 <li>Hiring developers to implement chat, iOS</li>
</ul>
I implemented all of the above-mentioned features myself, usually as the sole contributor. There are other features in the app that I did not develop: chat and the old broadcast functionality that leveraged chat, written by another developer that implemented a third-party service. I needed to rewrite the latter as it was not something that was suitable for the long-term.
Technologies I used for this project:
<ul>
 <li>Ruby on Rails</li>
 <li>Node.js</li>
 <li>native Android with Kotlin</li>
 <li>Postgres</li>
 <li>MongoDB</li>
 <li>Vue.js</li>
 <li>various API&rsquo;s</li>
</ul>
When I left the project, the app on the Google Play Store had a 5-star average review.

Junipurr Jewelry, a luxury body jewelry wholesale company that works directly with piercers, approached me to develop an ear piercing jewelry curation tool that they can embed in their existing Shopify website in their existing mobile apps on Android and iOS.
Body piercers would use Junipurr&rsquo;s new ear curation tool with their clients to help them visualize what new jewelry can look like alongside their existing pieces.
<h3>Features</h3>
The following features are available in the app:
<ul>
 <li>A piercer can&nbsp;take a picture&nbsp;of their client&rsquo;s ear with existing jewelry and upload it to the app. They can also use a&nbsp;picture from their photo gallery.</li>
 <li>The client and piercer can choose from a catalogue of jewelry available in the app and see what it would look alongside their existing pieces</li>
 <li>Users can&nbsp;filter&nbsp;jewelry by material (yellow gold, rose gold, white gold), and jewelry type (ring, studs, studs with gems, etc.)</li>
 <li>Users can&nbsp;drag and drop&nbsp;jewelry on the canvas, and&nbsp;resize&nbsp;as needed</li>
 <li>Curated pieces can be added to the piercer&rsquo;s&nbsp;Shopify&nbsp;cart</li>
 <li>Users can&nbsp;download&nbsp;and&nbsp;share&nbsp;the completed image curation to their Android and iOS devices</li>
 <li>The curation tool is&nbsp;white labeled&nbsp;so it can be themed with a custom brand to support multiple businesses that Junipurr works with</li>
</ul>
<h3>Tech Stack &amp; Challenges</h3>
The curation tool is built in JavaScript/TypeScript using React. It uses HTML5 Canvas. It was built as a standalone tool that would implement an interface that the hosting Shopify site would provide.
The jewelry curation tool needed to be embedded in their Shopify website which would be accessed via their existing mobile apps:
<ul>
 <li>a&nbsp;React Native&nbsp;app for Android which implemented a community&nbsp;web view&nbsp;plugin for the&nbsp;Shopify&nbsp;store</li>
 <li>a native iOS app written in Objective-C which implemented a native Safari web view for the Shopify store</li>
</ul>
This unique stack added a few interesting challenges with regards to interacting with the native layer on both Android and iOS from an HTML5 canvas in a web view in a native mobile app, and in the case of Android, via a web view via React Native.
In order to support exporting an image to the native devices via a JavaScript app in a web view in React Native for Android and support all of the Android versions that Junipurr supported, I needed to develop a&nbsp;React Native plugin&nbsp;that supports exporting images as a base64 string:&nbsp;<a href="https://www.npmjs.com/package/react-native-save-base-sixty-four">react-native-save-base-sixty-four</a>&nbsp;&ndash; This plugin also has full support for iOS.
This standalone JavaScript application interacts with the native app layers via a web view (and in the case of Android, React Native) to trigger native functionality like alerts, opening native share sheets, saving images to gallery, getting images from the gallery, getting images from the camera, and more.
<h3>Download</h3>
The curation tool can be found in the Create tab in the Junipurr Jewelry apps on Android and iOS.

Tenova is a technological group working in the iron-making industry. Tenova HYL hired me to develop an event logging app for the&nbsp;management of internal events and processes.
Tenova HYL, Mexico, builds plants that process the iron ore. An important step of the construction of a plant is the commissioning which follows the construction and assembly of the equipment. It is a test period before the plant is delivered to the customer.
Tenova HYL needed an event logging app to facilitate the&nbsp;reporting and sharing of events across the globe. They needed a&nbsp;user-friendly&nbsp;platform with which to record events quickly, as well as print out lists of events. The resulting application is powerful in terms of functionality, and runs very quickly.
They needed to be able to&nbsp;upload supporting documentation and images&nbsp;to each event. The solution includes an easy-to-use drag-and-drop interface with which to share files.
They also needed to be able to print lists of events so content that needed to be printed has been&nbsp;print-optimized&nbsp;so users can print directly from the browser.
The resulting product is a web application solution powered by the ProcessWire content management system and framework.
The application is being used at more than three locations globally and growing.
<ul>
 <li>Quick, powerful event logging&nbsp;app using the ProcessWire content management system and framework</li>
 <li>Content can be filtered by date range or other criteria including department, equipment area, and user</li>
 <li>Content is keyword-searchable</li>
 <li>The event logging app features&nbsp;multiple user roles and permissions&nbsp;to ensure only some users have access to sensitive parts of the application</li>
</ul>
All photos and text content are sample content.
