I’m an engineer in California. I write mostly about programming, and in the past have written about organizational behavior, logic, and poetry. I also keep a small website at ted.io.

I was an early software engineer at Simple, building banking software for humans.

I was then a systems engineer at GitHub, and later served as VP of Engineering and CTO there. I also worked as CTO for Brandcast, and have done some small open source projects over the years.
