PROFILE
V-cshekar
Over four months, Shekar contributed to the sonic-net/sonic-mgmt repository by building and enhancing automated test workflows for network device reboot and upgrade scenarios. He implemented OS-version-aware logic in Python to stabilize reboot history retrieval, reducing test flakiness across multiple Sonic OS versions. Shekar expanded test coverage to validate both CLI and gNOI-based reboot mechanisms, introducing fixtures and instrumentation for improved observability. He also delivered gNOI-based DPU reboot support and hardened test reliability by unifying reboot flows and removing failure masking. His work integrated Python scripting, network management, and test automation, resulting in more reliable CI pipelines and robust upgrade validation.

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.

Mar 1, 2026March 2026 was focused on delivering a robust DPU reboot workflow and expanding validation coverage in sonic-mgmt. The work enabled gNOI-based DPU reboot support, unified reboot handling across gNOI and CLI, and hardened the reboot test suite to reduce masked failures and improve end-to-end reliability. These changes strengthen system availability, accelerate incident response, and provide stronger validation for DPU reboot scenarios across production-like environments.
