Applied AI / Backend-Focused Full-Stack Developer based in Tampere, Finland — originally from Bilbao, Spain.

I design and ship LLM-native services end to end — from hexagonal backend architecture and agent platforms through to the React interfaces people actually use. That range is the point: I can take an AI feature from system design all the way to the UI without handing it off.

Most recently that meant an agent platform (~14k LOC) with a provider-agnostic LLM layer, exposed over FastAPI and an MCP server, instrumented with OpenTelemetry and covered by unit, E2E and mutation tests. It sits on a decade of production work — APIs, SDKs, data pipelines processing millions of records, and migrations like Heroku to AWS/Kubernetes.

Agentic coding tools (Claude Code, OpenCode) are my default way of building, while I still own system design, testing and production tradeoffs myself.
