I build and evaluate LLM agents for secure, production-ready automation.
SpainWhat I'm looking for
I build AI agents and tailored LLM automations for Spanish SMEs at Gia SL, designing document processing, retrieval workflows, and production integrations from client discovery through solution delivery. I also researched whether refusal-direction removal increases autonomous offensive capability in open-weight models, releasing code and data for my IEEE SaTML 2027 submission.
Previously, I designed industrial OT/ICS network architectures and implemented Claroty and Nozomi Networks solutions at Inetum. Alongside my Computer Engineering degree at UPM, I’ve built a PyTorch speaker-verification system and delivered end-to-end React websites.
