Worked on reliability hardening for webhook traffic in the Azure/fleet repository, focusing on backend development using Go and Kubernetes. Developed and integrated a readiness guard for the webhook server, ensuring that the server was fully operational before the hub-agent marked the pod as ready. This approach prevented premature routing of traffic to partially initialized services, thereby improving deployment safety and stability. The solution involved adding readiness checks at the hub-agent level, which enhanced the lifecycle reliability of webhook-related components during deployments. The work addressed a critical bug, contributing to more robust and predictable behavior in production environments handling webhook traffic.
