Javier Pintos — AI Engineer | RAG, LLMs, AI Agents & Automation

About

I'm an AI Engineer and Senior Software Engineer with 25+ years of experience building production software for international clients and technology companies.

Today, I focus on Generative AI, Retrieval-Augmented Generation (RAG), AI agents, LLM applications and intelligent automation.

My background in full-stack engineering allows me to build AI products end-to-end — from LLM orchestration and backend APIs to frontend applications, infrastructure and deployment.

I work with technologies and patterns such as Python, FastAPI, OpenAI APIs, LangChain, LangGraph, MCP, embeddings, semantic search, vector databases, tool/function calling, structured outputs, LLM evaluation and automation workflows.
