Overview

Led the architectural design and phased migration of a legacy monolith to a cloud-native platform. The system now handles 2M+ daily active users with 99.99% uptime.

Key Decisions

  • Event-driven architecture using SNS/SQS for decoupling services
  • Blue-green deployments via Kubernetes and ArgoCD for zero-downtime releases
  • Infrastructure as Code with Terraform across multiple AWS accounts

Results

  • 60% reduction in infrastructure costs
  • Deployment frequency increased from monthly to daily
  • P99 latency reduced from 800ms to 120ms
