Senior Software Engineer
I build calm, reliable web and mobile products with Angular, React and Symfony, from the first sketch to production.
−10 mAbout
I started my career as an IT project manager at ING Bank France, where I learned how software serves real people and real deadlines.
After 18 months travelling through 18 countries across Asia, Oceania and South America, I founded Jinbei Studio to design and build websites and web apps for businesses, and I have been shipping code ever since.
Today I am a Senior Software Engineer at Imagine Human, working across Symfony and Angular in an agile team. I care about clear architecture, maintainable code and interfaces that feel effortless.
Jinbei comes from jinbei-zame (甚兵衛鮫), the Japanese name for the whale shark: the gentle giant of the ocean. Steady, curious, and built to go the distance.
