Hello

This is the homepage of Christopher Bonhage, a human.

I am a full-product software engineer with an affinity for retro-computing, open source, web technologies, and building “the simplest thing that could possibly work”.

Lately I have been tinkering with homebrew Nintendo 64 development using LibDragon.

You can also find me on Twitter, GitHub, and LinkedIn.
