Ranjan Kumar

I am an AWS and Google Cloud Certified Solutions Architect and DevOps Engineer with 2+ years of hands-on industry experience in AWS, GCP, Kubernetes, Docker, Terraform, CI/CD, and cloud infrastructure. I currently work as an L2 Cloud Solution Architect, where I design and manage cloud-native environments, Kubernetes/EKS deployments, infrastructure automation, CI/CD pipelines, monitoring, logging, and production workloads.

I have practical experience with Jenkins, GitHub Actions, ArgoCD, AWS CodePipeline, Terraform, Helm, Prometheus, Grafana, CloudWatch, and ELK, along with AWS and GCP services. I have also worked on production microservices platforms, disaster recovery, high availability, and multi-environment infrastructure.

As a DevOps tutor, I focus on hands-on and practical learning. My teaching approach is to explain concepts from the fundamentals and then implement them through labs, real-world scenarios, troubleshooting exercises, and end-to-end projects. I aim to help students understand not just the tools, but how DevOps practices are applied in real production environments.
