  CI/CD Pipeline with AWS ECS Fargate

  Production-style automated deployment pipeline where every commit to main builds a secure Docker image, scans vulnerabilities, pushes to ECR, and triggers zero-downtime rolling deployments on ECS Fargate. Architected with modular Terraform for AWS VPC, Multi-AZ subnets, Application Load Balancer with health-check targets, and IAM roles configured via OIDC for keyless GitHub Actions authentication.

  Cloud Observability Stack on AWS

  Full observability and telemetry system monitoring microservices on AWS EC2 with custom Grafana dashboards, Prometheus time-series metrics, Alertmanager incident routing, and Node Exporter. Containerized via Docker Compose on EC2 instances. Implemented PromQL alerting thresholds for CPU spikes and memory exhaustion with automated webhook triggers to Alertmanager.

  Serverless URL Shortener on AWS

  High-throughput serverless URL shortening service using AWS Lambda, API Gateway HTTP API, and DynamoDB with Base62 collision-safe hashing, atomic hit counters, and TTL-based automated record expiry. All cloud resources fully declared in Terraform. Achieved sub-10ms redirect response times with API Gateway caching and zero-idle cost scaling.

  Kubernetes Cluster & GitOps Deployment

  Resilient Kubernetes application infrastructure orchestrated with Helm charts, automated Nginx ingress routing, Cert-Manager SSL certificates, and declarative GitOps pipelines. Configured resource limits, Horizontal Pod Autoscalers (HPA), persistent volumes, ConfigMaps, and cluster role bindings ensuring zero configuration drift.

  Production-Grade CI/CD Pipeline

  Built automated pipeline — push to main triggers Docker build, ECR push with immutable git SHA tags, and zero-downtime ECS Fargate deployment with rolling update and circuit-breaker rollback. Provisioned 14 AWS resources with Terraform — VPC, public/private subnets across 2 AZs, ALB, ECS cluster, task definitions, security groups, CloudWatch logs; remote state in S3 + DynamoDB locking. Implemented OIDC federation eliminating static AWS credentials; least-privilege IAM scoped to exact repository; ECR lifecycle policy expiring untagged images after 7 days reducing storage costs.

  Production-Grade GitOps Platform on EKS

  Architected GitOps platform on AWS EKS — ArgoCD auto-syncs manifests from GitHub with self-heal, prune, and automated sync; Kustomize base/overlay pattern for environment-specific config. Provisioned EKS with Terraform using Spot Instance node group across 4 instance types reducing compute cost by 70% vs on-demand; OIDC provider for IRSA (IAM Roles for Service Accounts). Configured HPA with CPU (60%) and memory (70%) thresholds scaling pods 2→6; deployed kube-prometheus-stack via Helm — Prometheus, Grafana, Alertmanager, kube-state-metrics, Node Exporter.

  Cloud Observability Stack

  Deployed full observability stack on AWS EC2 — Prometheus scraping 3 targets at 15s intervals; instrumented Node.js app with prom-client exposing HTTP request rate, P95 latency, error rate metrics. Built Grafana dashboards from scratch using PromQL; configured 5 Alertmanager rules (AppDown, HighErrorRate, HighCPU, HighMemory, DiskSpaceLow) with Gmail SMTP routing.

  Serverless URL Shortener

  Built fully serverless URL shortener — Lambda (Python 3.12) + API Gateway HTTP API v2 + DynamoDB PAY_PER_REQUEST; auto-scales to millions of requests at near-zero cost with no servers to manage. Collision-safe code generation via DynamoDB conditional writes; atomic hit counters; TTL-based auto-cleanup after 90 days; least-privilege IAM and OIDC-authenticated GitHub Actions deployment.
