Project ideas

• Build a full CI/CD pipeline that lints, tests, builds a Docker image, pushes it to a registry, and deploys to a Kubernetes cluster via GitOps (ArgoCD) on every merge to main.
• Provision a reproducible cloud environment from scratch with Terraform (VPC, load balancer, autoscaling group, managed DB) and configure the hosts with Ansible.
• Stand up a complete observability stack (Prometheus + Grafana + Loki + OpenTelemetry) for a sample microservice app, with alerting rules and a dashboard that surfaces the four golden signals.
