🛠️ Tech Stack

• Languages: Node.js 20 (Backend), React 18 (Frontend)
• Frameworks: Express, Vite, Tailwind CSS
• Infrastructure: Terraform, AWS EKS, VPC, IAM (IRSA)
• GitOps: ArgoCD, Argo Rollouts, Kustomize
• Observability: Prometheus, Grafana, Loki
• Service Mesh: Istio (Traffic Shifting)

📦 Features

• Zero-Touch Deployment: Push to main triggers image build, ECR push, and K8s manifest update.
• Canary Strategy: 20% traffic shift to new API versions with automated health checks.
• Multi-Env Promotion: Environment-specific overlays (Dev/Staging/Prod) managed via ApplicationSets.
• Micro-Frontend Ready: React UI served via Nginx with reverse proxy to backend.
• High Availability: Multi-AZ node groups with Spot instance cost optimization.

🚦 Getting Started (Local)

1. Clone the repo.
2. Run docker-compose up.
3. Open http://localhost.

🏗️ Deployment (AWS)

1. Initialize Terraform: terraform init && terraform apply.
2. Configure AWS Secrets in GitHub: AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY.
3. Push to main branch.
4. Access ArgoCD Dashboard: kubectl get svc -n argocd.

💼 Resume Bullets (Add to your profile!)

• Architected a production-grade GitOps platform using EKS, VPC, and ArgoCD, reducing deployment manual intervention by 100%.
• Implemented advanced Canary deployment strategies with Argo Rollouts and Istio, enabling 20% traffic shifting and automated rollbacks based on 5xx error rate thresholds.
• Engineered a scalable multi-environment CI/CD pipeline with GitHub Actions and Kustomize, achieving zero-downtime deployments across Dev, Staging, and Prod.
• Automated Infrastructure as Code (IaC) with Terraform modules for modular VPC and EKS cluster management, utilizing IAM Roles for Service Accounts (IRSA) for least-privilege security.
• Enhanced system reliability by integrating Prometheus and Grafana for real-time application monitoring and automated health-based rollouts.
