Jose P.

I build production-ready AI systems with Python, FastAPI, LangGraph and RAG. I help companies turn internal documents, business knowledge and repetitive workflows into reliable AI products. My core expertise includes: • RAG systems with citations, hybrid search and reranking • AI agents and multi-agent workflows with LangGraph • FastAPI backends, async processing and API integrations • PostgreSQL, Redis, Pinecone and vector databases • Document ingestion, OCR and structured data extraction • Docker, testing, logging and production hardening I can build a new AI application, improve an existing RAG or agent system, or turn a fragile prototype into a maintainable production service. I focus on retrieval quality, reliability, latency, observability and clean backend architecture.
