Project 1: End-to-End CI/CD Pipeline

Cloud Engineering Architecture

What: A full CI/CD pipeline for a simple web app using GitHub Actions. Build → Test → Security Scan (Trivy) → Docker Push → Deploy to AWS (EC2 or ECS).

Why it works: Shows you can connect the most common tools in a real workflow. This is the core ask in 80% of junior DevOps JDs.

Project 2: Infrastructure-as-Code AWS Environment

What: A complete, documented Terraform project that creates a production-like VPC — public/private subnets, NAT gateway, EC2 bastion host, RDS in private subnet, security groups with least privilege. Everything in modules.

Why it works: Shows architectural thinking, not just "I can run terraform apply."

Project 3: Kubernetes Deployment with Helm

What: Package your app as a Helm chart. Deploy to minikube or EKS free trial. Include HPA, liveness/readiness probes, resource limits, ConfigMaps, Secrets.

Why it works: Shows K8s production patterns, not just basic kubectl apply.

Project 4: Full Monitoring Stack

What: Prometheus + Grafana + Alertmanager on a real or local server. 3 custom dashboards. 5 alert rules. Alertmanager routing to Slack or email. Document everything.

Why it works: Monitoring is universally required and almost universally missing from junior portfolios. You immediately stand out.

Project 5: GitOps with ArgoCD

What: Two repos — one for app code, one for K8s manifests. ArgoCD watching the manifests repo. Show drift detection and auto-sync in a README video/GIF.

Why it works: GitOps is the direction the industry is moving. Showing you know it signals senior-level thinking.

Project 6: DevSecOps Pipeline

What: Add security gates to an existing CI/CD pipeline: SAST (Semgrep or SonarQube), dependency vulnerability scan (Trivy or Snyk), container image scan, secrets detection (TruffleHog). Block the pipeline on CRITICAL findings.

Why it works: DevSecOps is one of the hottest hiring areas in 2026. Security-aware DevOps engineers command 20–30% premium.

Project 7: Cost Optimization Dashboard

What: A script or Lambda function that queries AWS Cost Explorer API daily, identifies top 5 cost drivers, and posts a summary to Slack. Bonus: auto-tag untagged resources.

Why it works: Shows business awareness beyond just "keeping things running." FinOps is increasingly a core DevOps responsibility.

💡 Pro tip: Each project should have a detailed README with: what it does, architecture diagram, how to run it, what you learned, and what you'd do differently. Hiring managers read these. Make them count.
