Worked on sonic-net/sonic-swss, focusing on backend reliability and network management. Addressed VLAN-based FDB flush issues by updating fdborch to prepend the correct VLAN prefix, ensuring accurate MAC entry removal and preventing stale data in the forwarding database. Improved consistency between CLI operations and actual database state, reducing troubleshooting time. In a separate effort, stabilized LAG task processing in PortsOrch by correcting invalid field handling, introducing precise control flow to prevent state inconsistencies during port configuration. Utilized C++ for both bug fixes, demonstrating skills in network programming, backend development, and unit testing to enhance data-plane correctness and operational reliability.

Jun 1, 2026June 2026 — Sonic SWSS (sonic-net/sonic-swss): Stabilized LAG task processing in PortsOrch with a targeted bug fix. Corrected invalid LAG field handling in PortsOrch::doLagTask to prevent processing of invalid tasks and ensure correct task sequencing. The patch strengthens LAG reliability for port configurations and reduces risk of state inconsistencies in production. Commit: 98b1a7a0622b35d053f9969e994a7dc891151d80. Technologies demonstrated include C++, loop-level state management, and careful code-quality improvements through precise control flow.

May 1, 2026May 2026: Focused on VLAN-based FDB flush reliability in sonic-swss. Implemented fix in fdborch to prepend VLAN prefix 'Vlan' to VLAN IDs when resolving ports for VLAN FDB flush, ensuring actual MAC entry removal and consistent VLAN management. The change prevents false success messages and stale MACs during fdbclear -v <vid>, improving data-plane accuracy and network-management reliability.
