I build the backend that makes AI actually work.
Systems that scale, pipelines that ship, and infrastructure that holds under pressure.
Senior engineer with 5+ years designing production-grade backends, AI pipelines, and knowledge systems. I go from whiteboard to working system. APIs, agents, graphs, and everything in between.

Looking for the next hard problem
Interested in senior roles at product companies building in agentic AI or knowledge infrastructure. If you are working on something technically ambitious in that space, I want to hear about it.
