• Supported a US client's containerized B2B platform across development, staging and production AWS environments — multiple ECS Fargate services behind an Application Load Balancer, with RDS, Route 53 and Linux hosts — troubleshooting incidents across ECS/EC2, load balancing, databases, IAM, VPC networking and the OS layer.
• Held a weekly on-call rotation: triaged CloudWatch and PagerDuty alerts, assessed customer impact, executed documented rollbacks and recoveries, and authored root-cause analyses for production incidents.
• Rebuilt a half-manual release process into an automated GitHub Actions pipeline — tests, security scanning, image versioning, staged deploys and a gated production rollout with automatic rollback — shortening deployments and eliminating console-based production changes.
• Migrated manually-created AWS resources into reusable Terraform modules with remote state, state locking, pull-request plans and drift detection — ending configuration drift and making environments rebuildable from code.
• Improved observability by replacing static-threshold alarms with golden-signal and composite service-health alarms, each tied to a runbook — cutting non-actionable alert noise and speeding triage.
• Automated recurring operations with Python, Boto3, Lambda, EventBridge and Systems Manager — patch-compliance reporting, non-production scheduling and resource-health checks.
• Remediated IAM, vulnerability, encryption and configuration findings from AWS Config, Inspector, GuardDuty and Security Hub; supported secret rotation and backup/restore validation.
