Amadeu Serras
Full-Stack Engineer · TypeScript · React · Node.js
👋 About
Self-taught developer who came up through The Odin Project, then spent 1.5 years mostly on a large-scale Nestlé project — 20+ developers, international team. My title was frontend, but the work stretched further: I led full-stack user stories, pushed code quality standards across the team, and took on some of the harder refactors on the project.
After that I spent 8 months travelling through Mexico and built Zeronotes: a full-stack notes app with a custom drag-and-drop engine (no libraries), end-to-end encryption via the Web Crypto API, and a clean DDD architecture in TypeScript across the full stack. I wanted to prove I could own a product end-to-end.
Looking for a team with a high technical bar and real ownership across the stack, the kind of work where you can go deep and ship things that matter.
