// about me

Based near Knoxville, TN. I've been building Android apps since the early days of the platform, shipping across accessibility tools, weather apps, audio processing, computer vision, and CRM. Open to senior and staff mobile roles.

I care about clean architecture, tests that catch real bugs, CI that fails fast, and code the next person can actually work with. I write Kotlin and Swift natively. A significant portion of my work is contract work that never makes it onto a public GitHub profile: a whiteboard camera app, a relationship CRM with 400+ unit tests, and an AI-assisted diagnostic platform.

Engineered

Clean architecture, dependency injection, and real CI/CD. Multi-module Kotlin, Hilt, and MVVM written for the engineer who inherits it.

>_

Tested

Unit tests on business logic, not just smoke tests. 260+ on Elsie, 400+ on Rolo CRM. I write tests because bugs in production are expensive.

Shipped

Play Store submissions, release signing, crash reporting, and remote config rollout. At Digital Turbine, the carrier apps I built features for reached millions of daily users across AT&T, Cricket, and U.S. Cellular.
