I take new ideas to revenue.

I build the first version of new products — the working build that closes the round, lands the first customers, and gets into real use. Deep on AI when it matters, plain software when it doesn't.

Who I am

An operator with research-grade depth.

I'm hands-on in production code most days — and equally comfortable in a board meeting or in front of investors. I've shipped research-grade systems to enterprises that pay real money. I know which ideas are worth building and which ones aren't.
