Product
Engineer.

I ship full products from database to UI. Self-taught, endlessly curious, and always building something on the side.

About

Self-taught. Product-minded. Building since 2019.

I'm Fidalgo — a software engineer based in Aveiro, Portugal.

In 2018, I decided it was time for a change. I started teaching myself JavaScript before work, fell in love with it, and in January 2019 I quit my job to go all in. Six months later I landed my first engineering role at Mindera in the UK, where I grew into a full-stack developer — most notably working on Dunelm, one of the UK's largest home furnishings retailers.

Today I'm a Senior Product Engineer at Prolific, building with Python and Vue. But my heart is in the React and Node ecosystem — TypeScript, Tailwind, Hono, tRPC, and Postgres are what I reach for when I'm building for myself.

Outside of work, I build my own things. Zerosum is a budgeting app I built from scratch — a real SaaS product with real users. I like solving problems that I personally have, and turning them into something others can use too.

Writing

Soon.

No posts yet — but they're coming. I'll be writing about building products, technical deep dives, and lessons from shipping side projects.
