The human behind the pixels

Hello, I’m Calvin.

I spent 24 years solving problems in the Army. These days, I solve them with code, community, and an unreasonable number of browser tabs.

I build software that helps people connect, learn, recover, explore, and occasionally survive a Minecraft night. Each project here is personal, practical, and made with heart.
