Founder & Solo Developer — Long Beach, California
Marine Corps veteran turned software developer, building mobile apps for service members and veterans. Every app here ships from one desk in Long Beach.
I served as a Finance Tech (MOS 3432) in the Marine Corps, then used the GI Bill to finish a degree in Environmental Studies while picking up JavaScript and HTML on the side. I spent years in GIS and environmental consulting—Phase I and II site assessments—before eventually going all-in on software development.
I'm a single dad raising two daughters, Dahlia and Violet. The studio is named after them. Balancing that with disability and development work isn't always clean, but it gives me a pretty clear filter for what's worth building: things that solve a specific, real problem for a real person.
The military apps came out of that same instinct. Promotion prep and fitness standards are stressful, high-stakes moments for enlisted members—and the tools available to them are often either behind a paywall, bloated with unnecessary features, or just not built by someone who's been there. I've been there. So I build these things the way I'd want them.
I started with a PT calculator for one branch, got feedback from actual users on Reddit, and iterated fast. That's still how the apps evolve—feedback first, then build.
E5 and E6 WAPS prep with AFH 1 review, flashcards, quick drills, and SJT practice. The SJT depth was the specific gap users kept mentioning.
