Worked on the sonic-net/sonic-swss repository to enhance the stability and reliability of ACL handling in backend systems. Focused on resolving a critical bug in the AclRange::remove logic, which previously risked infinite loops and memory corruption. Applied strong C++ skills to update the loop structure, ensuring correct iteration over ACL range objects and preventing out-of-bounds access. Validated the fix by testing orchagent stability and verifying accurate SAI error logging. Demonstrated expertise in backend development, debugging, and memory management, contributing to a more robust codebase. The work emphasized careful patch verification and attention to detail in C++ backend environments.
