LLM/RAG · agentic systems · production data pipelines
Computer Science graduate with a dual degree in Business Administration and an MSc in Artificial Intelligence Applied to Financial Markets, combining engineering depth with quantitative and business understanding. I have hands-on experience building production ETL pipelines on AWS and shipping LLM-based systems — from RAG and agentic applications to data-driven analytics platforms. I take projects from concept to production, turning complex problems into scalable, intelligent tools that deliver measurable impact.
Ingeniero Informático con doble titulación en Administración y Dirección de Empresas y un Máster en Inteligencia Artificial Aplicada a los Mercados Financieros, combinando una base técnica sólida con visión cuantitativa y de negocio. Tengo experiencia práctica construyendo pipelines ETL en producción sobre AWS y desarrollando sistemas basados en LLMs — desde aplicaciones RAG y agénticas hasta plataformas de analítica de datos. Llevo los proyectos de la idea a producción, transformando problemas complejos en herramientas escalables e inteligentes con impacto medible.
- FiscalPilot — Agentic SaaS acting as a virtual CFO for Spanish freelancers: PSD2 bank-account sync, automatic IVA/IRPF tax reservation, expense classification and idle-cash investment proposals — all under human-in-the-loop approval and full auditability (GDPR · EU AI Act · MiFID II). Built on a deterministic tax engine with an agentic LangGraph reasoning layer. Python · FastAPI · LangGraph · Claude API · Supabase · Next.js · PSD2 (GoCardless). Private — available on request.
- RAG for European Financial Regulation — Master's Thesis (TFM) — Empirical study designing and evaluating RAG systems over the full hierarchy of EU financial regulation (Regulations, RTS, ESMA Q&As, CNMV criteria): a modular pipeline, a public benchmark of validated Q&A pairs, and evaluation of chunking, embeddings and generator LLMs on retrieval (Recall@k, MRR) and generation (faithfulness, relevance) metrics, following RAGAS and LegalBench-RAG.
