Fullstack developer and AI engineer based in Cali, Colombia. I take web products from zero to production and build the AI agents that run inside them: React/Next.js on the front, Python and Node on the back, AWS underneath.
Right now I'm an AI Engineer at Funnelchat, where I build Superagentes (LLM/RAG agents that talk to leads using each company's own data) and NOVA, an assistant that operates the whole platform for the user (FastAPI on AWS). I'm also finishing Systems Engineering at Pontificia Universidad Javeriana Cali.
