The front-end developer that loves design and user experience
I'm a Thomas, a design enginer with 6 years of experience working at the front of the front-end.
I code designs with HTML, CSS, JavaScript and SVG. I collaborate with design teams on design and user experience. If you have trouble coding responsive, accessible and cohesive designs, I'm probably the person you are looking for.

Case studies
Web projects are complicated! What are the problems I faced, what were the contexts I worked in, and what did I bring to the table? Those are the questions my case studies articles try to answer.
Rethinking the engineering and processes of interface creation at Arkea
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 CO2 Account
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.
