Ashish Alok focused on backend development for the sonic-net/sonic-swss repository, addressing a critical bug in ACL range handling during February 2026. He identified and resolved a logic error in the AclRange::remove function that previously risked infinite loops and memory corruption. Using C++ and leveraging strong debugging and memory management skills, Ashish updated the loop logic to ensure correct iteration over ACL range objects and prevent out-of-bounds access. He validated the fix by confirming orchagent stability and proper SAI error logging. This work demonstrated careful attention to reliability and depth in patch verification within a complex C++ backend environment.
