About

I'm a generalist who thrives on building, whether that's software, games, tools, or physical projects. I love finding the right solution to a problem and seeing it executed well. From indie XR games, custom apps, and game development tools to 3D-printed designs and hands-on DIY work, I focus on creating things that feel intuitive, thoughtful, and delightful to use.
