Code Reviews

Frequently Asked Questions

Who are you, anyway?

Hi! I’m Jonathan Hall. I've been programming most of my life, and I've been programming in Go for nearly a decade.

These days, I'm one of the hosts on the Cup o' Go podcast, the weekly Go news show, creator of the Boldly Go YouTube channel, and daily go blogger. I've written Go for many well-known companies and open-source projects, including several you almost certainly use already. I'm the author and maintainer of a popular open-source library written in Go, Kivik, and co-maintainer of GopherJS, the Go-to-JavaScript transpiler. I am also an active contributor on StackOverflow.
