Engineering Modern C++ Systems
Building Cross-Platform High-Performance Applications on Windows, macOS & Linux (C++20/23, CMake, Modules, Coroutines, Production CI/CD)

Modern software systems demand more than just working code—they require performance, portability, scalability, and production-grade reliability . Yet many C++ developers struggle to move beyond feature-level programming into the world of true systems engineering .

Engineering Modern C++ Systems is a comprehensive guide for developers who want to design and build high-performance, cross-platform C++ applications that run reliably across Windows, macOS, and Linux . This book bridges the gap between language knowledge and professional systems architecture, showing how modern C++20/23 features can be used to engineer real-world production systems.

Instead of isolated examples, the book walks you through the architecture of a complete cross-platform system, demonstrating how modern C++ features work together to create scalable and maintainable software. You will learn how to design systems that are portable by architecture, performant by design, and maintainable for the long term.

Inside this book, you'll explore how modern C++ enables high-level abstraction without sacrificing performance , using techniques such as zero-cost abstractions, compile-time interfaces, and cache-aware system design.

You’ll learn how to: Design portable system architectures that run consistently across Windows, macOS, and Linux Apply modern C++20/23 features including Modules, Concepts, Ranges, and Coroutines in real systems Build scalable software using layered architecture and platform abstraction layer s Optimize applications with cache-aware memory layouts, SIMD vectorization, and data-oriented design Implement high-performance concurrency models using coroutines, thread pools, and asynchronous workflows Manage complex projects using modern CMake and reproducible build systems Integrate dependency management with vcpkg and Conan for enterprise-scale projects Build reliable software using sanitizers, fuzz testing, static analysis, and continuous benchmarking Design cross-platform CI/CD pipelines with GitHub Actions and automated multi-platform builds Package and distribute software across platforms using MSI, DMG, DEB, and RPM packages Beyond coding techniques, the book also teaches the engineering mindset required for modern systems development—including performance budgeting, architectural tradeoffs, dependency management, and long-term maintainability.
A fully developed capstone project architecture runs throughout the book, demonstrating how real-world C++ systems evolve from foundational design principles to production deployment.
Whether you are building high-performance services, cross-platform desktop tools, infrastructure software, or system-level applications, this book provides the architectural strategies and practical techniques used by professional C++ engineers.
