I'm a data scientist and I look for hard problems to solve. Hair on fire "This is causing lemon-law recalls and we can't solve it." type problems - I've done a few of those. I have 15+ years experience helping companies plan, prototype, and productionize sane data science solutions.

I love avant garde problems, and have a pretty unique skillset. I've worked with names you know in automotive, aviation, tech, and other spaces. Recently I've been working with Oil & Gas - Production estimates, pricing, failure analysis, and other interesting things.

I've worked on projects including LLMs, knowledge extraction, automotive part failure prediction, vehicle route planning in constrained environments, translation, maintenance optimization, automated sports highlights, maritime piracy, and more.
