🚀 Freelance Full-Stack Developer — Go | TypeScript | React
I've been writing code for over 20 years — it's not just my job, it's my passion.
I focus on delivering clean, scalable, and maintainable software — backed by strong code quality and architectural thinking.
I'm Jean-Baptiste Demonte, a passionate full-stack developer and freelance engineer.
I've been writing code for over 20 years — it's both my job and my hobby.
I’ve spent most of my career in startups, often from the ground up — designing systems, building teams, and shipping real products.
Along the way, I’ve also been CTO and co-founder, leading tech teams, scaling products, and helping raise funding for ambitious projects.
I love environments where I can have real impact, learn fast, and shape things from the ground up.
Today I focus on Go, TypeScript, and React, and I care deeply about clean code, good architecture, and developer experience.
I'm also into retro-gaming, AI, and regularly follow MOOCs to keep learning.
Whenever I can, I contribute to open source — it’s my way of giving back 🌍
