York, PA

I build things that listen, move and ship.

Voice assistants, robots, security hardware, games, 3D prints and websites, built from the idea to something that works.

[01]About

Code, circuits and everything between.

I’m Chris, from York, Pennsylvania. I build across software and hardware: an AI voice assistant with its own plugin engine, a servo head that recognises faces, a Wi-Fi testing handheld on a board it was never made for, and a Roblox game where the server does not trust the client.

I also run HZR Tech, where I build and look after websites for local businesses.
