Websites and apps,
actually shipped.
I design and ship native mobile apps. Six are live on the App Store and Google Play right now. I also build custom websites and optimize existing apps. You work with me directly, not a project manager.
Three things I’m actually great at.
App builds from scratch, optimizing apps that already exist, and custom websites. Pick one or mix — I work on all three.
App in 30 Days
Full MVP build — design, frontend, backend, App Store submission, plus 30 days of support after launch. Flat rate, no surprises.
App Optimize
Got an app that works but feels rough? 30 days of cleanup — UX polish, bug fixes, AI feature additions, and App Store screenshot overhaul.
Custom Website
Hand-coded, fast, built for search. You own everything when we’re done — no monthly platform fees, no hostage code.

LinkLoop: From Personal Need to the App Store
My daughter has Type 1 Diabetes. The existing apps weren't cutting it. So I built LinkLoop — a real-time CGM monitoring app with Apple Watch support, Care Circle sharing, and AI-powered insights. Now it's helping other T1D families too.

Serving the Greater Sacramento Region.
App and web work is fully remote, but I'm based right here and meet local clients in person when it helps.
