Quick portfolio
I make complicated software work in the real world.
Right now I’m an Executive Director and the CTO at Zolvat. I helped take the company through EMI licensing and built much of the technical foundation it runs on. We launched in 2025. I lead the engineering work, but I’m still hands-on with the difficult parts.
Before that, I worked on advertising systems handling more than half a billion impressions a day, security and architecture engagements, shops, mobile apps, and a math-learning project I built with my father. I’m happiest fixing a real problem, documenting it clearly, and leaving the people and systems around it better than I found them.
How I work
I lead the work, and I still build.
I move between product decisions, system design, operations, and delivery. I’m at my best taking a fuzzy problem, finding what matters, and building something that works in practice.
