Senior Software Engineer
Senior software engineer building secure, scalable systems — from SaaS signature platforms used by thousands to microservices serving hundreds of thousands of users. I lead teams, ship products end to end, and care about clean architecture as much as shipping fast.
Building systems that hold up
I design and ship secure, scalable software — from signature platforms trusted by thousands to microservices serving hundreds of thousands of users.
Based in France, I work across the stack: backend architecture, distributed systems, and frontend delivery, with a strong bias toward clean architecture, TDD, and pragmatic engineering. I've led development teams from zero to product, hired and mentored engineers, and co-founded a SaaS platform from the ground up.
