Inside the Book
The 15 chapters move from foundations and requirements through systems modeling, architecture, UI/UX, Agile project management, version control, testing, CI/CD, data and APIs, cloud deployment, security, maintenance, professional ethics, and final project integration. A comprehensive glossary supports review and reference.
Each chapter combines core concepts with examples, review questions, hands-on exercises, and a project milestone so that knowledge is applied to a complete software system as the book progresses.
