Building
Shipping Badminton Manager — a web app to organize badminton sessions, players and matches, built with Next.js and TypeScript.
I build web products that are fast, reliable & beautiful.
I'm Charles — full-stack JavaScript developer based in Lille. 10+ years delivering for clients in consulting (ESN) — banking & finance, retail/e-commerce, public sector and industry. I ship modern web apps from idea to production: clean UIs, solid APIs, no bloat.
- 9+ Years of experience

- ∞ Coffees per day
— Positioning
Builder, not just coder.
A decade of consulting taught me that shipping code isn't enough. I think product, care about the business outcome and long-term maintainability — the way a reliable team member does, not a solo hobbyist. The result: web apps that ship faster, scale cleaner, and feel right to use.
