Hi, I'm Dalen

I'm an app developer and Gallatin Applications is where I build and showcase my apps and projects. I specialize in Kotlin and Compose Multiplatform, focusing on simple, reliable software and thoughtful user experiences.

Tooling: IntelliJ IDEA, Android Studio, Gradle, GitHub

Beyond app development, I maintain a personal blog where I share my thoughts on software engineering, lessons learned from solo development, and tutorials focusing on Kotlin and Compose Multiplatform.

About Me

I’m a mobile software developer with a non-traditional path into the industry. I studied computer science before moving into telecommunications, where I worked on network infrastructure, fiber, and large-scale system deployments. That experience built a strong foundation in systems thinking, troubleshooting, and delivering reliable systems in production.

I returned to software development with a focus on building and shipping apps. I started with Swift and SwiftUI, moved into Android with Jetpack Compose, and ultimately specialized in Kotlin Multiplatform and Compose Multiplatform to share business logic and UI across platforms. I’ve designed and shipped Android and iOS apps with an emphasis on local-first architecture, clean domain modeling, and performance-conscious UI.

Today, I focus on continuing to build and iterate on my apps while deepening my expertise in Kotlin and Compose Multiplatform. If you’re looking for an experienced Kotlin or Compose Multiplatform developer who can own features end-to-end, my socials and resume are linked below.
