Over six months, contributed to the sonic-net/sonic-mgmt repository by building and enhancing automated test and upgrade workflows for network devices. Focused on stabilizing reboot and upgrade processes, the work included implementing OS-version gated logic for reboot history, expanding test coverage to validate both CLI and gNOI-based reboots, and consolidating DPU reboot logic for maintainability. Used Python, gRPC, and test automation frameworks to improve reliability, reduce test flakiness, and ensure robust CI execution. Addressed fixture management issues and introduced post-reboot device checks, resulting in more dependable upgrade paths and streamlined validation for both production and continuous integration environments.

Jun 1, 2026June 2026 focused on stabilizing the GNOI upgrade test path in sonic-mgmt by fixing fixture-related failures and ensuring reliable CI execution. Key changes center on test_upgrade_gnoi.py: imported missing fixtures (ptf_grpc, ptf_gnoi, setup_gnoi_tls_server from grpc_fixtures) and added gnmi_tls to the test signature, resolving fixture resolution errors and preventing collection-time failures.

May 1, 2026May 2026 monthly summary for sonic-mgmt: Delivered a targeted DPU upgrade workflow enhancement, consolidating DPU reboot logic into a single function and enabling explicit gRPC routing headers. This change reduces complexity, improves reliability of DPU upgrades, and enables precise routing control during upgrades. Updated upgrade flow to use the new perform_gnoi_reboot_dpu in _upgrade_one_dpu_via_gnoi, and expanded test coverage for GNOI-based upgrades. Demonstrated strong Python tooling, gNOI/gRPC skills, and test automation, resulting in clearer traceability and faster upgrade cycles.

Apr 1, 2026Month: 2026-04 — Sonic management upgrade reliability and test stability. Delivered a reliability fix for the gNOI upgrade process by introducing post-reboot device checks in sonic-mgmt. The change updates perform_gnoi_upgrade to call ensure_gnoi_tls_server post-reboot to verify TLS server readiness and device state before continuing upgrade verification, reducing flaky test outcomes and increasing confidence in upgrade paths. This work improves CI feedback loops, accelerates deployment readiness, and reduces customer upgrade risk. Technologies demonstrated include Python scripting, upgrade/test harness integration, reboot flow handling, and TLS validation. Business value: more reliable upgrades, faster time-to-value for new Sonic features, and lower operational risk for gNOI-based workflows.
