A little about what I do
Websites.
Software.
Things you can hold.
I’m Justin. I run 3D Print BC, work on websites through JR Media Group, and build software for the jobs I keep doing by hand.

Away from the homepage
I like figuring
things out.
A replacement part that’s hard to find. A website that needs fixing. A repetitive job that could use a better tool. Those are the kinds of projects that keep me interested.
This site brings my businesses and side projects together. It’s a place to see what I’m building and get in touch if there’s something you’d like to work on.
