Worked on the airbnb/chronon repository to improve build reliability by addressing a compatibility issue in Thrift code generation. Focused on ensuring that Thrift-generated Java code consistently uses the project-configured JDK within Bazel builds, this work reduced build failures and minimized debugging time related to JDK mismatches. The solution involved updating build system configuration and integrating Bazel and Thrift workflows to honor the specified Java environment. By aligning code generation with project settings, the developer enhanced the stability of Java builds and provided traceable improvements linked to issue tracking and commit history, demonstrating attention to reproducibility and maintainability in complex build systems.
