About Me

I’m a DevOps Engineer working primarily with containerized applications in AWS environments.

My main focus is containerization, secure architecture design, and operating reliable production systems. I build environments where applications are easy to deploy, monitor, and scale.

Most of my work involves:

  • Designing container-based microservices architectures
  • Building and optimizing Docker images using multistage builds
  • Managing container workloads on ECS
  • Creating CI/CD pipelines for automated container deployments
  • Designing secure AWS networking (VPC, ALB, WAF, Route53)
  • Monitoring and implementing observability using CloudWatch, Prometheus, and Grafana
  • Managing staging and production environments

I focus on making systems stable, scalable, and predictable.

Core Expertise

Containerization

  • Docker (multistage builds, image size optimization, runtime tuning)
  • ECS microservices architecture
  • Kubernetes fundamentals

Cloud Infrastructure

  • AWS (ECS, ECR, EC2, VPC, ALB, Route53, S3, WAF, Auto Scaling, CloudWatch)
  • Secure architecture design
  • Environment isolation (staging / production)

Infrastructure as Code

  • Terraform (modular and reusable infrastructure design)

CI/CD

  • Jenkins
  • AWS CodePipeline
  • CodeBuild
  • Container image lifecycle management

Monitoring & Observability

  • CloudWatch
  • Prometheus
  • Grafana

Production Experience

  • Migrated services from monolithic architecture to container-based microservices
  • Optimized Docker builds to reduce image size and deployment time
  • Implemented secure networking and traffic management
  • Designed scalable ECS-based production environments
  • Built automated pipelines for consistent container deployments
  • Managed live production rollouts and monitoring
