Who am I?

I'm a freelance data scientist with a unique background combining military precision with advanced analytics expertise.

My journey from military pilot to data scientist has shaped my approach: structured, reliable, and focused on delivering measurable business value. I specialize in developing end-to-end data solutions—from pipelines to dashboards—and translating technical outcomes into clear, actionable insights for stakeholders.

In recent years, I’ve worked in complex, high‑stakes environments where data directly supports operational decision‑making. I’ve built predictive maintenance models, developed LLM‑powered AI tools, and designed data governance frameworks that make information accessible and actionable. These experiences taught me how to bridge business and technology in a way that turns advanced analytics into solutions people actually use.
