Selva worked on the sonic-net/sonic-sairedis repository, focusing on enhancing the maintainability and extensibility of bulk operations in C++ for embedded systems. He addressed a bug in the DECLARE_BULK_SET_ENTRY macro, which previously hardcoded the object type, by parameterizing it to support multiple entry types. This change enabled bulk set operations across various object types, not just route entries, and aligned the macro’s behavior with existing bulk operation patterns. His work involved low-level programming and network programming, resulting in a more standardized and future-proof codebase that reduces regression risk and simplifies onboarding of new entry types for the project.
