Revamped the incident management process using AWS CloudWatch, leading to a momentous improvement in system availability for critical services. Implemented CICD pipelines for code/artifact delivery on both prod and non-prod environments. Setup and Monitored Cluster Usage and Application performance using Prometheus and Grafana. Led the successful migration of critical systems to a Kubernetes-based architecture, resulting in a significant improvement in deployment efficiency and a noticeable reduction in resource costs by leveraging containerization. Setup Alerts on Grafana dashboards and broadcast them to notification channels. Automated application installation and build process using MAVEN and Gradle. Configured Jenkins Build/Deploy Pipeline to store the build artifacts in Artifactory repository. Planned and executed disaster recovery failover drills to ensure availability of critical services. Documented best practices and procedures to deploy applications on Kubernetes clusters via Helm Charts within the organization. Analysed telemetry data to suggest improvements during Capacity Planning meetings. Optimized several pipelines and automated toil-heavy processes to improve efficiency.
