Sobre mí
I’m a backend and AI engineer building Node.js APIs, LLM applications, voice-agent platforms, and intelligent document search. My experience includes Vertex AI, OpenAI integrations, vector search, SQL databases, and Google Cloud. I’ve developed ETL pipelines managing millions of product records and deployed cloud microservices with automated CI/CD. I help businesses connect AI with reliable backend systems—from chatbots and search to data processing and workflow automation. Message me to discuss your project.
