Ketan Jain — DevOps & Cloud Engineer

About

Hey, I'm Ketan, a DevOps & Cloud Engineer passionate about building, automating, and scaling reliable cloud systems on AWS. I focus on turning complex infrastructure challenges into repeatable, observable, and automated workflows.

I spend most of my time in the terminal, writing Terraform modules, architecting containerized deployments on ECS Fargate & Kubernetes, and configuring CI/CD pipelines with GitHub Actions.

I don't just follow tutorials — I engineer production-style systems from scratch with deep attention to high availability, security (OIDC/IAM), zero-downtime rollouts, and cost efficiency.

LIVE FEATURED

CI/CD Pipeline with AWS ECS Fargate

2026

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

2026

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

2026

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.
