DevOps & CI/CD Challenges
DevOps & CI/CD challenges put you inside the work of shipping software safely and often. You'll develop skills in Version Control with Git, build CI/CD Pipelines, and package services with Docker, then run them through Kubernetes orchestration.
From there you'll handle the harder edges — GitOps, Helm chart authoring, Multi-cluster Kubernetes, Service mesh, and Zero-downtime deploys — working with Ansible / Terraform automation the way platform teams actually do. Each challenge you solve earns a verified credential you can share with recruiters.
