Who I Am

I'm a Senior DevSecOps Engineer at Practical DevSecOps (PDSO), based in Hyderabad, India. I specialize in integrating security into every stage of the development and operations lifecycle, building production-grade CI/CD pipelines, and automating cloud infrastructure at scale.

With years of hands-on experience in managing, securing, and automating systems, I focus on open-source technologies like Docker, Kubernetes, Terraform, Jenkins, and Ansible to help teams ship software that's fast, reliable, and secure.

I'm recognized as a Docker Captain, AWS Community Builder, and hold a Certified Kubernetes Administrator (CKA) credential — reflecting my deep involvement in the cloud-native ecosystem.

What I Do

In-Depth Tutorials

Step-by-step guides on Kubernetes, Docker, Jenkins, Terraform, Ansible, and more — written from real production experience.

Real-World Projects

Full DevSecOps pipelines — Netflix, Reddit, Uber, and Zomato clones deployed with Jenkins, Docker, Kubernetes, and security scanning baked in.

Security-First Approach

Every project integrates Trivy, SonarQube, OWASP checks, and Vault — because security shouldn't be an afterthought.

Community Teaching

14K+ YouTube subscribers, 200+ videos, and a growing blog — making DevSecOps accessible for engineers at every level.

Core Expertise

Docker Kubernetes Jenkins Terraform Ansible AWS Azure GCP CI/CD ArgoCD Prometheus Grafana Trivy SonarQube Python Bash Linux Git Helm Istio

Work With Me

Available for blog posts, meetups, public speaking, and video collaborations on DevSecOps topics.

Why I Started MrCloudBook

In my career, I've faced countless challenges navigating the rapidly evolving world of DevSecOps. I know how overwhelming it can be — there are endless tools, constantly changing best practices, and a steep learning curve at every turn.

That's why I built MrCloudBook: a platform where theory meets practice. Every tutorial, project, and guide on this site comes directly from my real-world experience. I believe the best way to learn is by doing, so I focus on hands-on implementations you can follow along with, rather than abstract concepts.

Whether you're just getting started with Linux and networking, or you're an experienced engineer looking to deepen your Kubernetes or security skills, I've designed the content to meet you where you are and take you further.

Through the blog and my YouTube channel, I want to build a community of engineers who don't just learn theory — they apply it to solve real-world problems, land better jobs, and build systems they're proud of.
