About the Book
Build better systems. Make informed architectural decisions. Engineer for production.
The System Design Engineering Handbook is a comprehensive, practical field manual for software engineers, backend developers, technical leads, and software architects.
Organized into 62 parts and 624 sections, this handbook covers the principles, engineering trade-offs, and practical techniques behind designing, reviewing, scaling, and operating production software systems.
What You'll Learn
- System design foundations and requirements engineering
- Distributed systems, concurrency, consistency, and fault tolerance
- Database architecture, caching, and data modeling
- APIs, networking, messaging, and event-driven architectures
- Scalability, performance, reliability, and observability
- Security architecture and production operations
- Microservices, distributed transactions, and architectural patterns
- Real-world case studies, failure analysis, and design trade-offs
- Practical checklists, decision frameworks, and architecture reviews
- Applying system design principles with AI coding agents
What's Inside
- 62 comprehensive parts
- 624 organized sections
- 24 technical diagrams

About the Author
Fadi Al-Najar
I'm Fadi Al-Najjar, a software engineer specializing in full-stack development, backend engineering, and software architecture.
I design and build software applications, with a focus on backend systems, database architecture, APIs, and production-ready solutions.
My work involves developing real-world software systems and solving engineering challenges related to scalability, reliability, maintainability, and system design.
I'm the author of the System Design Engineering Handbook, where I bring together engineering principles, architectural patterns, and practical decision-making frameworks into a structured reference for software developers and architects.
Earn $8 on a $10 Purchase, and $16 on a $20 Purchase
We pay 80% royalties on purchases of $7.99 or more, and 80% royalties minus a 50 cent flat fee on purchases between $0.99 and $7.98. You earn $8 on a $10 sale, and $16 on a $20 sale. So, if we sell 5000 non-refunded copies of your book for $20, you'll earn $80,000.
