I build software where agents do most of the work, and I make sure it holds up in production.

Co-founder and CTO at Omnia. Living on the Asturian coast, in the north of Spain.

What I do

At Omnia we help marketing teams get their brand seen and recommended by AI assistants like ChatGPT, Claude and Gemini. People ask those assistants what to buy now, so being part of the answer matters.

How I work

My background is distributed systems, concurrency and reliability engineering. These days that shows up as infrastructure for agents: orchestration, sandboxes, retries, recovery, and safety rails that fail closed.

I work AI-first. I barely write or read code myself anymore, and I ship more than ever. Most of my job is now designing the system, writing clear intent, and judging outcomes.

Before Omnia: query engines at Prisma, cloud backends at Hasura, real-time analytics at Fastly and backend and data infrastructure at GitHub.

On the side

Off the clock

Mostly I’m outside: travelling by van, camping, surfing, bikepacking and hiking with my wife, a bunch of friends, and our dogs, Lua and Maui.

I also write creatively, without AI, and shoot analog black and white film. Both stay private for now, so here is the rest of me on a roll of film.
