Senior
Product
Engineer.
I build products people actually use — and I care about every part of that experience. 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 Product Engineer at Prolific, where I focus on making the platform better for everyone who uses it — from leading accessibility initiatives and building design system components, to improving internal tooling and mentoring engineers across teams. When I'm building for myself, I reach for React, TypeScript, Tailwind, and Postgres.
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.
Selected Work
Zerosum
Zero-based budgeting made simple. A full-stack SaaS I built and run with real users.
Liga do Tinto
A custom fantasy league dashboard for my friend group. Replaced a clunky website and messy spreadsheets with proper stats and split-season tracking.
Movie Library
A React app for browsing and discovering movies. One of my earlier projects that helped me learn React and working with external APIs.
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.
