I get to teach people how to program with Go. How cool is that? 😁

Education

B.S. in Computer Science

Work

I create Go courses at Calhoun.io

Go, Ruby on Rails, PostgreSQL, and pretty much anything else useful for web development.

I'm currently working on a course about advanced web development with Go. It will cover how to setup a React SPA along with a Go API, doing local dev with docker, deploying, and more. Get in touch if you want to learn about it - jon@calhoun.io.
