About
Building at the edge of what's possible
I've spent two decades building products that sit at the intersection of technology, data, and human insight. From early-stage startups to scaled platforms, I've learned that the best products emerge from deep understanding—of users, systems, and the messy reality between them.
Currently, I'm exploring how AI is reshaping the way we work, create, and make decisions. I write about product intuition, engineering systems, and signals from the AI landscape.
