• Design and implemented the centralized monitoring solution using Prometheus, thanos and alert manager.
Built the agreed monitoring solution in a centralized EKS clusters.
• Deploying the k8s resources using helm chart and fluxcd/ArgoCD(GitOps).
• Deployed Grafana in EKS to create and share the performance dashboards with the wider team and stakeholders.
• Improved the joiner/leaver process by automating the mapping of user/permission sets and AWS accounts using SSO.
• Auto assignment of user to Cognito groups using custom developed process (DynamoDB and lambda) for the applications using AWS SSO for authentication.
