Hi, my name is

Jonathan Montenegro

AI Engineer · Fullstack

I build AI systems that survive the real world.

About me

Who I am

I build things. Drawn to problems where something's broken and needs fixing. I move without being pushed: find the gap, fill it. I've worked where getting things wrong had real consequences — it made me more careful, not slower.

What I'm looking for: AI-first teams building autonomous agents and LLM-powered systems in production. RAG pipelines, tool-calling, event-driven agent coordination. Remote, fast-moving, real engineering challenges where the AI layer has to survive messy real-world data.
