PROFILE

Tatsuyuki Kobayashi

Worked on the android/nowinandroid repository over a two-month period, focusing on codebase maintainability and build system modernization. Delivered a UI and design system cleanup by removing unused experimental API annotations from Composable functions and classes, which improved code clarity and reduced implicit opt-in handling. Subsequently, simplified the build configuration by removing vectorDrawables.useSupportLibrary from the Gradle Kotlin DSL, aligning the project with newer Android tooling and reducing maintenance overhead. Demonstrated disciplined change management and a focus on long-term stability using Kotlin, Jetpack Compose, and Gradle. No major bugs were fixed, as the emphasis was on proactive code and build improvements.
