Computer vision · LLM systems

I build computer-vision and LLM systems that hold up in the real world.

Final-year AI engineer. I take machine-learning models out of notebooks and into systems that run on real hardware — real-time perception, LLM pipelines, and the deployment around them.

Real-time vision for worker-safety monitoring

Industrial fall detection that runs live on a single mid-range GPU — pose, tracking, segmentation and a temporal model behind one observable service, with no fabricated numbers.

    Clearance-aware GraphRAG

    An agentic GraphRAG system where a user's clearance is enforced inside the retrieval path — the model never sees a chunk the caller isn't allowed to read, so it cannot leak it.

    Partial observability in deep RL

    My bachelor's thesis: a reproducible benchmark for how reinforcement-learning agents cope when they can only see part of the world — and which architectures recover the missing state.

About

I'm a final-year AI engineering student at the University of Vigo, more interested in the gap between a model that works in a notebook and a system that works on real hardware than in either one alone.

Most of my hands-on work has been in computer vision — real-time perception for an autonomous racing platform with Auria — and in LLM pipelines, including a RAG system for clinical data normalization at MicroPort. The thread through both is the unglamorous part: reproducible training, clean deployment, and evaluation that's honest about where things break.

I work in Spanish and English.
