• Containerize services using Docker and manage their deployment and lifecycle within an Azure Kubernetes Service (AKS) cluster.
• Implement and configure a service mesh (e.g., Istio, Linkerd) to manage traffic, enforce security policies, and enhance service-to-service communication.
• Build and maintain a comprehensive observability stack, including distributed tracing, metrics, and logging (e.g., Prometheus, Grafana, Jaeger, ELK Stack).
• Collaborate with cross-functional teams, including DevOps and SRE, to ensure the reliability, scalability, and security of the platform.
• Troubleshoot and resolve complex issues in distributed systems.
