● Deployed and maintained 15+ web applications on AWS and GCP achieving 99.9% uptime, using Terraform IaC to automate provisioning and cut manual deployment effort by 40%. ● Engineered 15+ Github Actions and AWS CodePipeline CI/CD pipelines with stage-gated deployments, automated testing, artifact management, and rollback triggers across multiple microservices. ● Containerized workloads using Docker and Docker Compose, restructuring monolithic applications into microservices and standardizing deployments across dev, staging, and production with consistent image tagging and registry management via ECR. ● Owned Grafana and Prometheus observability dashboards with CloudWatch and Nagios alerting rules, reducing average incident response time by 30% and improving on-call production visibility. ● Resolved 90% of L1/L2 production tickets within SLA using journalctl log analysis, netstat/ss networking diagnostics, and curl-based endpoint testing; managed MySQL and PostgreSQL in staging environments, including basic backup and restore operations. ● Authored Bash scripts for cron-scheduled maintenance, log rotation, and health checks, reducing manual overhead by 50%; administered Linux servers via systemctl, user permissions, and security group management. ● Analyzed EC2 instance utilization through CloudWatch CPU and memory metrics, right-sizing over-provisioned instances from larger to smaller instance families, reducing monthly compute spend without impacting application performance.
