I'm Thomas

I code user interfaces for humans.

I am a freelance front-end developer focusing on user interfaces. I have 8 years of experience and live by the sea in Brittany, France.

If you have trouble making your websites and apps responsive, fast, accessible, or visually cohesive, I'm the right person for the job.

Freelance Works

Screen capture of the website mensfashioner

The Mens Fashioner crew hired me to help build their long-awaited men's lifestyle ressource, starting with the selection of the tech stack up to webdesign and the frontend development. My careful implementation of their design into tokens and components, combined with the strong wysiwyg editor of Kirby CMS, allowed them to compose a personal yet profesional looking website.

Screen capture of the website IMEC

IMEC had just finished reworking their website with a freelancer and were unhappy with the result, which did not look cohesive and did not felt profesional. I reworked the entirety of the stylesheets, cleaned and standardized the templates and components, and reworked the accessibility.

Screen capture of a live show by Gauthier Andres

When freelance journalist Gauthier Andres launched his daily talk show on youtube, he knew he had to diffuse it as a podcast. I built BOTOZ using Python, as a command line utility to transcode youtube videos into MP3 and XML files. BOTOZ is now a fully automated open source solution running in the background, and has served hundreds of episodes to thousands of listeners.

Screen capture of the website Bas Gros Poing

Bas Gros Poing is the longest running active website and podcast about fighting games in French language. Guillaume Brindon redesigned the website under my guidance, and I developped the whole frontend. The animations and design elements are inspired by arcade cabinets, character select screens, and the nineties esthetics.

Technical deep dives

Rethinking the engineering and processes of interface creation at Arkea

Photo of me

From 2018 to 2020 I joined the Arkea banking group as a UI engineer to help modernize the technical stack and processes. We moved from several intricate SASS codebases to a single library of components, flexible enough to support several designs and 100% WCAG compliant.

As this technical change restricted a very freeform design culture, I volunteered to participate in design meetings to help the designers, marketers and product owners understand how to work with a design system.

This team effort resulted in a sharp decline of interface, accessibility and responsive bugs. It reduced drastically the cost of making, delivering and testing user interfaces.

Printed letters, smart emails and modern blog stacks at Compte CO2

When I arrived at Compte CO2, the company was launching new products and needed a total revamp of all its frontend styles. With the help of a graphic designer we started a six month marathon, redoing everything from the main website to the blog, but also email templates and print styles for printed bank documents.

This short mission was a massive step forward in my career, as I was able to learn a lot about moderm JavaScript tooling and frameworks. I self-studied React and NodeJS before starting, and developed my first official component library for a client.

All those efforts resulted in a more cohesive vision for the company and a greater understanding of modern web development practices for me.
