The story behind the apps.

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.

Tools for service members, built by one.

What's coming next.

EPB Builder

A narrative-building tool for Air Force Airmen. Takes real work accomplishments and translates them into promotion-ready EPB language — the kind that actually reads like it belongs on a performance report.
