Jon Calhoun

Jon started programming at an early age (around 8-9) when introduced to Apple Basic. Since then he has been hooked, learning about web development, scripting levels in videos games, algorithm competitions, and more. He eventually discovered Go and loved the language, but felt the resources for newcomers was lacking which lead to him starting to create videos, tutorials, and other educational resources. Some of his more popular courses include Gophercises, a course composed of mini coding exercises each designed to teach something unique aspects of Go, and Web Development with Go, an in depth course that teaches how to build production grade web applications from the ground up in Go.
