Full-stack developer and applied AI.

Córdoba, Spain

I work on product and on business management software: ERP, accounting and tax compliance. I specialise in applied AI: RAG systems that answer from in-house documentation and agents that use tools through function calling.

Outside work I keep building: I contribute to open-source projects and develop my own.
