I'm the co-founder of Bugsnag (https://www.bugsnag.com), a popular real-time crash detection service for mobile and web applications, with Simon Maynard. I previously led the product team as CTO of Heyzap, helping scale the company to over 8 million users.
I've also built a number of popular open-source projects which you can find on GitHub (https://github.com/loopj).
