I currently work as a senior frontend developer at Leboncoin, the largest classified ads website in Europe.
Passioned by Javascript, I am up to date with matters such as a11y, performance optimization and web design in general. I enjoy working with vanilla JS or frameworks equally (mainly React and Svelte)
I am using task runners such as webpack/rollup on projects to automate as much as can be and improve productivity. I am familiar with the NPM ecosystem.
Among all paradigms, I like functional programming a lot. I like clean and tested code (unit/functional tests)
I contributed to a few SPA, showcase website, e-commerces, tracking tools and a design system.
