AI & systems architecture · Barcelona
I design and build the technical backbone of products: Go backends, system architecture, AI that does a real job. Freelance, remote or in Barcelona.
I build backend systems, design architecture, and help teams integrate AI into their products. I work as a freelancer - short or long engagements, remote or in Barcelona. No fluff, no upselling. If I can help, I'll tell you. If I can't, I'll tell you that too.
I help teams use AI tools effectively - not the hype, the actual useful parts. From developer workflows to product features.
I help you figure out how to structure things before you build them - or fix the structure when it's already breaking.
I write backend code, mostly in Go. APIs, data pipelines, services that need to handle real traffic.
You tell me what you need. I ask questions. No commitment.
What I can do, how long it'll take, how much it'll cost. No surprises.
I build, you review. I prefer short feedback loops over big reveals.
Own products, client work and systems where I combined engineering, architecture and judgment.
Buying rural land in Spain means betting €30,000+ on questions nobody packages cleanly. SueloMio answers them for an exact parcel from official public data.
A live climate instrument for Europe: every 10×10 m of ground, sealed or alive — and the nearest cool place when the heat turns dangerous.
Privacy-hardened Android OS built on LineageOS. I built the overlay system, network hardening, device identity rotation, Guardian modules, and a multi-provider AI agent.
Open-source device flashing platform. I built the CLI, web UI, custom firmware builder, and device support for flashing alternative operating systems on 200+ devices.
A marketplace attempt to help fund open-source projects. I worked on the backend, payment flows, and trust mechanisms before winding it down.
Education program needed better operations. I built systems to manage campus activities and student collaboration.
I design and build the technical backbone of products - backend architecture, AI integration, infrastructure. I've set up campuses with 400 machines, built price transparency platforms, and architected marketplace systems from zero to production.
I studied philosophy at the Sorbonne before training as an engineer at 42 Paris. That combination shapes every architecture decision I make - especially around AI, privacy, and autonomy.
I work best at the early stage of projects, when the decisions that will matter most haven't been made yet. If you're integrating AI into a product and want someone who thinks beyond the API call, let's talk.
If you have a project in mind, just reach out. Even if it's just an idea - I'm happy to chat and see if it makes sense to work together.
