About

Freelance .NET developer based in Canada, with 20+ years of full-stack experience. I build production web applications for small businesses from first conversation to deployment, and stick around for what comes after. My background spans enterprise healthcare platforms, agency client work, and independent projects. If you have a real problem that needs a real solution, I'd like to hear about it.

Rocket Descent

Rocket Descent is a lighthearted Phaser.io 2 prototype I created in 2018 during RKD Web Studios' website refresh. It was designed as a playful easter egg concept for the refreshed site, showcasing arcade gameplay, custom animation, and WebAudio integration in a short, self-contained experience. The concept was ultimately not included in the live launch, and the demo is included here with RKD's permission.

Built in connection with the 2018 RKD Web Studios site refresh.
