Worked on grpc/bazel-central-registry and tryretool/retool-helm, focusing on build reliability and deployment flexibility. Addressed a critical Bazel build failure in the Postgres module by exposing the pg_config_ext.h header and introducing a minimal presubmit example, which improved integration of libpq and reduced downstream build errors for both open source and internal users. Later, enhanced the code executor deployment in tryretool/retool-helm by adding support for extra containers, enabling more flexible and extensible Kubernetes deployments. Utilized technologies including Bazel, C/C++, Helm, and Kubernetes, demonstrating a methodical approach to dependency management, build systems, and DevOps workflows across both projects.
