Full-Stack Engineer · €55/hr · Lisbon
I'm Joao — full-stack engineer who treats AI as infrastructure. I take things from architecture to deployment, and I've seen enough projects die before launch to care about that last part.
Selected Work
Solo products, agent systems, and client work. All in production.
Full-stack SaaS for dive shops. Booking, payments, equipment tracking, staff and customer management — built solo, from schema to deployment. 197 tests, 13 verified user flows, pilot-ready.
Private or not yet public
18 AI agents across 6 coordinated swarms. Runs a 7-phase autonomous pipeline from market scanning to validated PRD generation, integrating Firecrawl, Google Trends, Ahrefs, SimilarWeb, and Product Hunt through MCP servers.
Private or not yet public

Why Work With Me
I don't just write code to spec. I figure out what needs to be built and build it — schema, API, frontend, deployment.
I use Claude and Codex heavily. I move faster than most teams of three, and it's still production code, not demos.
Years of OutSystems consulting too — if you've got legacy low-code sitting next to a modern stack, I know both sides.
Best fit: engineering teams that need senior capacity now and care about what they're shipping.
What People Say
“Joao is one of those rare developers who is as technically gifted as he is great to be around. On our Crop Controller project, he was lightning-fast and consistently ahead of the game. I quickly learned I could trust him with total autonomy over UI decisions, and he never let me down. He has a real knack for looking at a requirement and spotting how it might need to evolve, ensuring his solutions are truly built to last. More than just his skills, though, it's Joao's heart and hustle that make the difference. He's incredibly committed, has a stellar work ethic, and his happy, team-first attitude made every sprint better. Any team would be lucky to have him.”
