Selected Work
Edit Playlist, Hatch Baby
- Summary
- Built playlist editing for a Hatch Baby Android release using MVI architecture. A single immutable UI state drove the feature, making state transitions clear, predictable, and easy to test across both Add and Edit flows. Shipped on time with a stable experience and a strong foundation for future enhancements.
- Tech Stack
- Kotlin, Jetpack Compose, Coroutines, Flow, MVI
Routine Swap, Restore 3
- Context
- Restore 3 users needed a clearer way to swap routines without losing structure, while keeping behavior predictable around schedule constraints.
- Approach
- Built a focused swap flow with explicit state transitions and validation points, then refined interaction details with product and design to keep the experience fast and understandable.
- Outcome
- Delivered a stable first release that reduced workflow friction for users and established a maintainable foundation for future routine management improvements.
- Tech Stack
- Kotlin, Compose, Flow, ViewModel, Analytics Instrumentation
Android Architecture Modernization
- Context
- Legacy Android patterns were slowing feature work and making behavior harder to reason about across the codebase.
- Approach
- Led and contributed to modernization across key modules: Kotlin-first implementation, Coroutines/Flow adoption, clearer boundaries between UI/domain/data layers, and consistent UI state handling.
- Outcome
- Improved maintainability and testability, reduced architectural inconsistency, and made feature iteration and release execution more predictable.
- Tech Stack
- Kotlin, Coroutines, Flow, MVVM, Clean Architecture, CI
