ABOUT ME

Industrial Engineer who works End-to-End.

I understand the operation before touching the code. My path goes from international logistics to software development — not as a career change, but as a natural evolution: when you manage real operations, you learn exactly what a tool needs to work in the real world.

Today I build systems that solve problems I've lived myself: production SaaS platforms, data pipelines, process automation. With Next.js, Supabase, Python and TypeScript — and with the judgment of someone who knows the business from the inside.
