Senior full-stack engineer · Barcelona

Hi, I'm LucasBuilding software and figuring things out

I'm a senior full-stack engineer working on everything from frontend and backend to integrations and delivery at a luxury e-commerce company. Off the clock, you'll usually find me building an action RPG in Unity, a passion project inspired by god knows how many hours spent playing Diablo.

For years, I've wanted to write about software, side projects, my takes, and things I'm still figuring out, which has kept me waiting until I have it all sorted out. Spoiler alert: that was clearly never going to happen.

Having fun creating an ARPG

I started 2026 challenging myself to develop a video game. I started with an overambitious multiplayer prototype that felt too much for my free time, and it became the reference material for a smaller-scale single-player ARPG.

The shelf where my side projects live

Everything I build ends up on one of two Pis, where it either ends up being useful or doesn't. The first one holds the services I actually rely on. The second is where I break things, and eventually some apps graduate to the first one.
