Multi-Cloud Infrastructure Automation: Provisioned secure and highly available AWS, Azure, and GCP environments using reusable Terraform modules and Ansible, eliminating manual setup and standardizing dev/test/prod environments.

Kubernetes Platform Management: Administered multi-region EKS, AKS, and GKE clusters. Configured HPA, Ingress controllers, StatefulSets, RBAC, and secrets management for mission-critical services.

DevSecOps & Automated Security Gates: Integrated SonarQube, Trivy container scanning, Checkov IaC scanning, and HashiCorp Vault into Jenkins and GitHub Actions pipelines to enforce vulnerability checks prior to production release.

GitOps & Progressive Delivery: Implemented Argo CD and Helm to enable declarative Kubernetes deployments with automated rollback, supporting Blue-Green, Canary, and Rolling updates.

Full-Stack Observability & Incident Response: Built real-time Prometheus & Grafana dashboards, Splunk centralized log analysis, and Dynatrace/New Relic APM tracing to monitor SLIs/SLOs, reducing Mean Time to Resolution (MTTR).

Platform Engineering & Scripting: Created developer self-service templates and automation scripts in Python and Bash for health verification, routine operational tasks, and cloud cost optimization.
