Full-Stack Software Developer
Been modding games and breaking things since I was 12. Now I get paid to build them properly, and I'm always shipping something on the side.
About
I started writing code at 12, modding Minecraft, GTA San Andreas, and GTA V. That hobby turned into freelancing in 2016, and I've been building web apps and shipping side projects ever since. I went to Fanshawe College's co-op program to get my foot in the door professionally and came out with a 4.0 GPA. I'm based in London, Ontario, and there's always something I'm working on.
