Building AI tools, web platforms, and creative software.
Turning ideas into deployed products — fast.
01. about
I build things that work. Web apps, AI integrations, automation platforms, music production tools — if it involves code and creativity, I'm in.
Based in Ontario, Canada. One-man dev shop shipping real products for real clients. Every project in my portfolio is live, deployed, and used by actual humans.
When I'm not coding, I'm producing beats in Ableton Live or pushing the limits of what AI can do for creative workflows.
