📖 About

This repository documents my complete DevOps learning journey, covering everything from Linux fundamentals to production-ready DevOps practices.

Unlike scattered notes, this repository follows a structured roadmap designed to build a strong foundation while documenting real-world concepts and hands-on experience.

Each topic includes:

  • 📚 Beginner-friendly explanations
  • 💻 Practical commands
  • ⚙️ Hands-on examples
  • 🏗️ Real-world workflows
  • 🎯 Interview preparation
  • 📝 Personal learning notes

The goal is to create a centralized knowledge base that I can continuously improve and revisit throughout my DevOps career.
