Why it was needed
01As the feature set expanded, the architecture and release process had to mature without slowing the team down.
Fitness community service

Fitness / Community
Fitness service with discovery and community flows, backed by Android architecture and release automation.
Project overview
The Android side needed a structure that could support both the main service app and component apps while the team kept shipping.
Kookmin PT is a fitness service built around trainer discovery, center search, and community-like content flows. Beyond the product screens, a major part of the work was giving the Android team an architecture and release process it could keep shipping on.
In the implemented scope, the Kotlin Android app was reorganized around Single Activity, Clean Architecture, MVVM, and Multi Module patterns, with GitHub Actions and Firebase-based release automation added on top. It was an Android lead role focused on both product growth and team velocity.
What I built first
02I reorganized the app around Single Activity, Clean Architecture, MVVM, and Multi Module patterns, then added GitHub Actions and Firebase-based release automation.
Where this approach works well
03This fits Android service apps that mix discovery, community, and content flows while requiring team-scale maintenance.
