Independently Built and launched ClimbSpeed — production RAG for aviation

Education M.S. Computational Biomedicine, Pitt · B.S. Computational Biology, RPI

I build AI systems that ship to production and solve real problems. At J&J, I design multi-agent chatbots and data pipelines for CAR-T cell therapy manufacturing. Independently, I built and launched ClimbSpeed, a production RAG platform that helps student pilots prepare for their FAA knowledge tests.

My approach is measurement-driven: I build evaluation pipelines before features, validate architectural decisions with data, and simplify relentlessly. At ClimbSpeed, this meant a custom ReAct agent that outperforms complex validation layers, achieving 4.86/5.0 correctness across 230 benchmarked questions. At J&J, it means PySpark pipelines that normalize 17 heterogeneous datasets and chatbots that safely query regulated manufacturing data.
