• Led observability modernization by migrating from Micrometer to OpenTelemetry, enabling full-stack metrics, traces, and logs across distributed components in an event-driven architecture.
• Designed and implemented dynamic autoscaling for Apache Flink TaskManagers using Prometheus + Alertmanager, with advanced PromQL expressions and inhibition logic to prevent alert flapping.
• Automated Flink scaling by integrating Prometheus alerts with SSH-based self-healing scripts for scale-up and scale-down of VM-based resources, optimizing cost and resource utilization.
• Built and tuned complex PromQL alerting rules to monitor execution latencies, checkpoint performance, and resource bottlenecks in real-time.
• Improved system resilience by debugging and resolving Flink checkpoint failures, enhancing HA recovery with Zookeeper and HDFS integration.
• Evaluated and compared Flink deployment strategies (e.g., 1 TM with multiple slots vs. multiple TMs with 1 slot) to improve throughput and minimize backpressure.
• Developed Chef cookbooks to automate Prometheus installation and prometheus.yml configuration across environments; explored Chef Habitat for service orchestration.
• Created internal documentation, architecture diagrams, and reusable scripts to enable smooth onboarding, faster debugging, and consistent monitoring practices.
