Worked on runtime modernization and dependency management for the Shopify/discovery-apache-beam repository, focusing on improving compatibility and security across Python versions 3.9 to 3.12. Delivered three features over two months, including upgrading container base images, raising the minimum supported Python version, and implementing dependency pinning for libraries such as protobuf and grpcio-status. Applied build automation and Python packaging skills to ensure deterministic builds and safer deployments. Additionally, updated multiple dependencies to newer minor versions, enhancing security and access to recent library features. All changes were validated for cross-version support, streamlining onboarding and maintenance for multi-version Python environments.
