Worked on enhancing the aws-samples/awsome-distributed-training repository by delivering a feature that expanded HyperPod instance group configurability through optional training plan support. Leveraged AWS, CloudFormation, and Terraform to implement infrastructure as code solutions, focusing on improving both observability and onboarding reliability. Introduced automated Prometheus data source registration in Grafana, pre-configured dashboards, and per-node metric exporters, along with lifecycle script updates for streamlined monitoring. Added an ObservabilityConfig class to centralize configuration and profiling instrumentation, supporting advanced telemetry and profiling workflows. Addressed documentation quality by updating assets and resolving regressions, resulting in a more stable and maintainable distributed training platform.
