Worked on internal infrastructure improvements for the uber/NullAway repository, focusing on modernizing the Gradle build system. The main contribution involved refactoring build configuration by removing deprecated buildDir usage and adopting current Gradle APIs, which enhances build compatibility and maintainability. This update, implemented entirely in Gradle, did not introduce user-facing changes but reduced the risk of future deprecations and streamlined maintenance. The work also supported faster CI and build cycles by aligning scripts with modern tooling. Demonstrated skills in build configuration and infrastructure refactoring, contributing to the long-term health and reliability of the project’s continuous integration pipeline.
