Designed and maintained reusable GitLab CI/CD templates with standard stages for build, test, validation, security scans, artifact publishing, and code coverage. The templates support multiple languages and are now used by 25+ teams, reducing setup effort while improving consistency, retry handling, and logging reliability.
Created centralized CI/CD automation for frontend microservices with secure credential retrieval from Vault, artifact promotion to Nexus and S3, and deployment tracking in MongoDB. Added BlackDuck, SAST, and SonarQube quality gates plus a blue-green deployment strategy for zero-downtime releases.
Migrated 3+ applications from GitLab to GitHub Actions with zero downtime, cutting deployment time by 50%. The migration emphasized reusable workflows, safer rollouts, documentation, and team enablement for smoother adoption.
Automated AWS infrastructure across development, staging, and production using Terraform. Managed Kubernetes clusters with scaling and security policies while improving monitoring with Prometheus, Grafana, and CloudWatch for better operational visibility.
