Worked on the chalk-go backend to update and synchronize Protocol Buffer schemas across multiple services, enabling enhanced data handling, query execution, integrations, deployments, and management of environment secrets. The engineering effort focused on introducing new protobuf message types, such as OfflineQueryShardedParquetUploadInput, OutputRowOrder, and Venv in Resolver, to lay the foundation for future data ingestion and query features. Using Go and leveraging backend development skills with gRPC and Protocol Buffers, the work ensured schema consistency throughout the repository. These updates established the groundwork for improved data ingestion workflows, integration data management, and deployment observability across the chalk-ai/chalk-go codebase.
