Worked on the android/nowinandroid repository to modernize and secure the project’s build environment by upgrading core library dependencies. Focused on dependency management and build tools, the work included updating Retrofit to version 2.10.0 and aligning Robolectric and Roborazzi versions to ensure compatibility and consistent test environments. Using TOML for configuration, these changes reduced technical debt and improved build stability, laying a safer foundation for future development. No major bugs were addressed during this period, as the primary contribution centered on maintenance and risk reduction through careful consolidation of dependencies, supporting ongoing and upcoming feature work within the codebase.
