About

I'm a mobile developer who likes shipping. Ten years in mobile, five-plus of them in Flutter.

  • Technical Delivery Lead at Very Good Ventures, leading delivery of Flutter apps for clients such as Dutch Bros and Divine, and still writing code every day
  • On VGV's platform team, where my main open-source projects are Wingspan, the Very Good AI Flutter Plugin and the VGV AI CLI
  • Google Developer Expert for Firebase (since 2019) and Flutter (since 2025)
  • Part of the DevFest.cz team with GUG.cz, which I first joined in 2017; built the 2026 conference app and website
  • 50+ talks, including FlutterCon USA, FlutterCon Europe and mDevCamp
  • Previously CTO at Openvibe and senior lecturer at Czechitas
  • In my free time I build my own apps and odd experiments, because hacking on things is fun. I also own a beer fridge.
