DevOps Engineer with 3 years of experience in designing and managing cloud-native infrastructure on AWS. I have successfully handled high-stakes production workloads, including over 14 million emails per day during Black Friday and Cyber Monday, with zero incidents across Kubernetes, ECS, and multi-region architectures. I am skilled in CI/CD automation, infrastructure-as-code, and cost optimization at scale.

Experience

  • Drove end-to-end migration of dozens of legacy Jenkins pipelines to GitHub Actions, standardizing workflows across engineering teams and increasing deployment frequency while reducing maintenance overhead.
  • Designed and delivered a horizontally scalable, production-grade infrastructure for a coupon management service from DNS and ALB routing through ECS containers to Aurora RDS provisioned entirely via Terraform.
  • Built a fully automated GitHub Actions pipeline with a structured branching strategy, PR template validation, ECR artifact management, and Terraform-based infrastructure deployments enforcing mandatory PR approvals and a separate infrastructure change approval gate to ensure deployment security and compliance.
  • Owned infrastructure reliability for BFCM peak load of 14M+ emails/day with zero incidents. Led end-to-end readiness efforts including CPU, memory, and healthy-node alerting across all services; capacity reservation planning; and active-active multi-region deployments with Route 53 health checks for automatic failover, ensuring full disaster recovery coverage under peak traffic.
  • Led large-scale EC2 rightsizing initiative by analyzing CPU/memory utilization patterns, achieving substantial cost savings with a 0% request failure rate and no post-migration stability issues.
  • Managed Kubernetes workloads at 3,000+ RPS by implementing Horizontal Pod Autoscaling (HPA) and fine-tuning resource limits, ensuring consistent system resilience under peak load.
  • Architected Blue-Green deployment strategy using Route53 and ALB, eliminating deployment-related downtime and improving production release success rates.
  • Redesigned configuration propagation workflow between upstream and downstream systems, cutting global update time by 50% (30 min → 15 min).
  • Identified and resolved RDS bottlenecks through query execution optimization, reducing AWS RDS CPU utilization and improving application response times.
  • Developed responsive UI components using Handlebars and Backbone.js built and maintained MongoDB schemas engineered backend services with Spring Boot.
