Mastering Software Development — A Guide For Early Career Engineers
By Prof. Balwinder Sodhi, Dept. of CSE IIT Ropar (Website)

About the book

In the rapidly evolving world of technology, understanding how to build software is only half the battle - knowing why it's built that way is what sets a true engineer apart. Mastering Software Development is the definitive guide for early-career engineers who want to go beyond coding and understand the full lifecycle of modern software systems — from concept to deployment.

Drawing from real-world practice, this book helps you:
  • Grasp the core foundations of software design and architecture.
  • Apply user experience principles that enhance usability and engagement.
  • Master modern architectural patterns ─ from microservices to serverless.
  • Understand AI/ML and LLM-powered architectures shaping today's systems.
  • Implement testing, CI/CD, and observability to ensure quality and resilience.
  • Integrate everything into a cohesive, real-world system in the final capstone project.
Key feature: This book is interspersed with QR codes that takes you into a deeper dive into the topic in context.

Why Software Fundamentals Still Matter in the Age of AI

Even with "superhuman coders," human expertise stays essential.

  • Verification: Safety-critical software can’t be trusted without human understanding.
  • Resilience: Losing core CS knowledge creates systemic dependence on AI.
  • Oversight: Real software audit requires deep architectural and engineering insight.
  • Education: We still need theory, systems thinking, and the ability to challenge AI output.

AI won't make software engineers obsolete - it makes informed engineers indispensable. This book helps you stay in that role.
