About

About

I'm Lucas B, a senior software engineer based in Spain working on distributed systems and developer tooling.

Over the last decade I've shipped services handling millions of requests per day, led small engineering teams, and contributed to open-source projects. I care about clear thinking, clean abstractions, and code that's a pleasure to read six months later.

How I work

Contracts before code

A clear interface, a contract test, then the implementation. In that order.

Measure first, optimize later

Without data, every optimization is superstition.

Boring scales

Postgres, structured logs, reversible deploys. Boring survives the hype cycle.

Write for your future self

Six months from now, I'll thank myself for clear comments and good naming.
