I'm a data scientist, I'm looking for hard problems to solve. Hair on fire "This is causing lemon-law recalls and we can't solve it."[1] type problems.
I love avant garde problems, and have a pretty unique toolset (LLMs+KB, OR+ML, etc). I've worked with names you know in automotive, tech, and other spaces. Recently I've been working with Oil & Gas - Production estimates, pricing, and things I'm not allowed to talk about.
I've worked on projects including LLMs, knowledge extraction, automotive part failure prediction, translation, maintenance optimization, automated sports highlights, and more. I've also done some more interesting work including vehicle route planning in constrained environments.
Get in touch. Even if you're unsure, get in touch. Referals welcome. Email in profile.
[1] Yup. Done that. A few times.

I'm basically a jack-of-all-trades software engineer who's done extensive "founding engineer" work in the context of both VC-backed startups and for smaller contract gigs over a period of about 10 years.
I have strong technical foundations, good product sense, and have gone deep with AI/LLM tech both in the sense of being able to use it effectively, and in exploring the design space for products/tools leveraging it.
Tools I use most frequently these days: Typescript, node, React, pnpm+vite. I've also done extensive work with three.js in the past. I used to write a lot of Java and a bit of Objective C, have dabbled in Rust and Elixir.
I've done a lot of work in developer tools and data visualization of various kinds. Data-rich, non-traditional UIs with highly optimized UX, and rapid prototyping are my forte.
I've been basically on sabbatical for a while now, mostly taking the time to learn and build with AI. At some point in early 2024 I decided: okay, time to take this seriously, and have. After the long break, I'm ready to start something new!
