Worked on the Snowflake-Labs/sansshell repository to modularize the Raw Service by refactoring the raw client into reusable functions and exporting utilities for broader cross-service use. Focused on improving maintainability and testability, the work introduced explicit error types such as errFailedToDecode, enabling more precise error diagnosis and robust failure handling. Leveraged Go for implementation, with an emphasis on code refactoring and error handling best practices. Utilized Protocol Buffers and gRPC to ensure compatibility and extensibility across services. This foundational update set the stage for faster feature delivery and reduced incident rates by enhancing the resilience and clarity of the codebase.
