Gemtool

I'm a senior engineer building tools, backends, and experiences for Roblox and the web.

8+ years of experience, end to end. I've built and supported large-scale systems, delivering scalable and engaging experiences, and have contributed to big games and worked alongside some big names along the way. Open for new work.

Games With Active Players

A few of the games I've worked on that still have players today, not every project stays live forever.
