🦊 Some Mozilla projects I am proud to be part of ...

  • πŸ”₯ I am a founding team member of Firefox for iOS and later managed the team. I helped to ship many releases of this great browser for your iPhone and iPad. You can download it on the App Store.
  • 🀫 I came up with the idea for Firefox Focus for iOS. I contributed to it's initial development and also managed the team. After a short break, Focus for both iOS and Android is back in active development.
  • πŸ“¦ I built, managed and grew the Mozilla Android Components team, responsible for building a rock solid foundation for our Android Browsers, including Firefox for Android (Fenix) and Focus for Android.
  • πŸŽ‚ I managed the team that shipped Fenix 1.0, a full rewrite of Firefox for Android. The 1.0 release was tagged and celebrated on the last day of our all-hands meeting in Whistler, July 2019 🐻πŸ₯‚ That was a very proud moment after a mountain of work πŸ”

None of these projects would be a success without the contributions from team members, colleagues and contributors who have put in countless hours and insane amounts of energy 🦊 ❀️

😎 Some side projects that I've worked on over the years ...

  • 🍎 I worked on an 6502 Emulator called the Emulated Woz Machine (EWM) that can run Apple I and Apple II+ software like Frogger, Hard Hat Mack, Jaw Breaker and Burger Time. I wrote a series of blog posts about it's development. (Plain Old C)
  • πŸ“Ί I wrote a "Sad Mac" screen saver for macOS to bring back some nostalgia. Technically not impressive but a lot of fun to look at. (Objective-C)
  • ⌚️ I shipped AstroNote, a tiny WatchOS app with a REST API to send notifications to your wrist. (Swift, Go)
