Freelancer profile translated to English.

Description

I am an AI engineer dedicated to putting LLMs and RAG systems into production: assistants and search engines that answer about your own documents, with cited and verifiable answers, without invented hallucinations.

My best calling card is diarioboe.es, a platform I built from start to finish: it processes more than 200 daily publications from the BOE with AI and answers legislative queries with a hybrid RAG over millions of documents. It's in production, with paying users. It's not an experiment: it works every day.

I can help you with: AI assistants for your documentation, RAG pipelines (ingestion, embeddings, reranking, evaluation, and deployment), and integrating AI into your backend with Python/FastAPI and PostgreSQL.

I work by clear deliverables and design the solution with you before coding anything. If you want your documents to answer, let's talk.

Platform that transforms +200 daily BOE publications into accessible content with generative AI. I design and manage the system end-to-end: scraping and processing pipeline, LLM generation, and a hybrid RAG in production (BM25 + HNSW/pgvector vector search + reranking) over a corpus of millions of embeddings, with verifiable citations and regulatory validity tracking. Stack: FastAPI, Nuxt 4, PostgreSQL (pgvector/FTS), Valkey, Docker, custom orchestrator, and observability (Prometheus/Loki). Includes chat.diarioboe.es (legislative assistant with RAG) and an MCP server to query the BOE from Claude/ChatGPT. Product in production with paying users.
