What I'm looking for

I'm looking for a role where I can really dig into building AI systems that make a difference—especially in healthcare. Working in a startup sounds like a blast because I love moving fast and having a direct impact. Also, collaborating closely with leadership on fresh projects, like scaling a new medical platform, fits my experience perfectly.

I'm a Senior AI Software Engineer in Chicago with 7+ years in enterprise software, starting at Epic on healthcare apps and moving into AI platforms at Grayphite and Elastech. At Elastech, I built agentic workflows, realtime AI, and a RAG platform over 1M+ documents, which cut unsupported responses by 22% and improved latency by 35%.

What I like most is owning the full build, from backend architecture in Python, Node.js, and FastAPI to React frontends, cloud deployment on AWS, and production support when things get messy. One real tension was getting LLM features reliable enough for healthcare use cases, so I put in evaluation pipelines, hallucination checks, and guardrails instead of just shipping raw model output.

I’m most interested in full-stack and platform work where scale, data, and product quality all matter, especially in enterprise or regulated environments. Outside work, I keep up with LLM tooling, agent systems, and cloud architecture because this space changes fast and I like staying sharp.
