  • Entrepreneur
  • Founder
  • SwiftUI
  • Next.js/TypeScript
  • AI/LLM

I build products that solve real problems and move fast from idea to impact across mobile and web. I bring multi-year experience shipping and scaling products across mobile, web, and AI - reaching 20+ million users worldwide. As a previous co-founder of AVIMBU, I’ve built and delivered products end-to-end. I’m currently exploring new opportunities, experimenting with AI/LLM-driven ideas and identifying where technology can create real leverage.

Exploring my next venture

I’m currently exploring ideas for my next startup - experimenting, validating assumptions, and learning directly through conversations with founders, operators, and domain experts. My interests are broad, with a particular focus on robotics, aviation, and health.

Selective consulting

I take on a small number of selected engagements in iOS (SwiftUI) and Web (React/Next.js, TypeScript), where I can add meaningful leverage. Founder-level, hands-on support across product thinking, architecture, and execution.

Beyond work

Outside of work I enjoy staying active - running, gym training, golf, and skiing. Long walks with my dog help me reset, recharge, and think through new ideas.
