About

I don't just write code. I engineer products.

I'm Machado — a full stack developer from Portugal who builds production-grade systems. My work is measured by real user impact, not lines of code.

From real-time event platforms used by 1,500+ concurrent users to SaaS restaurant management systems, I obsess over performance, reliability, and developer experience.

My stack centers around Next.js, NestJS, and Supabase — tools I use to ship fast and scale with confidence.
