About

I’m an Android developer with a background in Java, Kotlin, pharmacy operations, and small business. I like practical software: tools that make a real task easier, remove friction, and produce something useful.

My current focus is building Android apps with Kotlin and Jetpack Compose, while also maintaining and presenting earlier Java Android projects as part of my development path.
