DevOps Engineer | Iceberg Tech Chennai / India Oct 2025 – Present

• Designed and deployed a production-ready multi-tier AWS architecture using a custom VPC with public/private subnets, achieving isolated backend and database layers for a CRM application serving live users.
• Architected an end-to-end delivery pipeline: S3 (static frontend) → CloudFront (CDN + SSL) → ALB (layer-7 routing) → EC2 private subnet (NGINX + backend) → RDS (MySQL), ensuring high availability, security, and scalability.
• Configured Route53 DNS with domains registered via BigRock; integrated ACM certificates for HTTPS enforcement across CloudFront and ALB endpoints.
• Built and maintained CI pipelines with GitHub Actions (build, lint, test) and CD pipelines with Jenkins (staging + production deployments), reducing deployment time and human error.
• Implemented full-stack observability: Prometheus + Grafana dashboards for HTTP request rate, error rate, and saturation (RED method); Loki for centralized log aggregation; Tempo for distributed tracing.
• Deployed AWS CloudWatch alarms and log insights to monitor EC2 health, RDS performance, and ALB 5xx error rates, enabling proactive incident response.
