Full-stack developer, tech lead & creative mind. I build web & mobile apps, APIs, tools, and sometimes… games and music 🎸

I’m a Symfony /JS framework specialist with 7+ years of experience, mixing clean architecture, product thinking, and Agile project management.

I believe:

• Clean code is a form of respect
• Refactoring is self-care.
• Architecture matters more than anything
• And learning never stops

And yes, my desk is always a mess.
