C++23 · Production-Grade

Modern C++ in Practice

A hands-on engineering guide for experienced programmers. Ownership, interfaces, failure boundaries, concurrency, performance, and verification — taught through real design pressure.

What You'll Learn

Engineering decisions, not syntax tours

Every chapter starts from a production problem and ends with decisions you can apply in real code reviews.

🔒

Ownership & Lifetime

RAII, move semantics, and resource boundaries that survive refactoring.

⚠️

Error Boundaries

Expected, error codes, and exceptions — when each one pays off.

🧩

Concepts & Constraints

Write generic code that fails at the call site, not deep in a template.

Concurrency

jthread, coroutines, structured concurrency, and cancellation that works.

📊

Performance

Data layout, allocation cost models, and benchmarking without lying to yourself.

🛡️

Verification

Sanitizers, static analysis, observability, and testing strategy for native code.

Who This Is For

Experienced programmers, C++ newcomers welcome

You already know how serious software gets designed, debugged, and deployed. You may be new to C++, but not to engineering judgment.

🏗️

Systems Engineers

Moving to C++ from Rust, Go, or Java for performance-critical work.

🔍

Senior Developers

Reviewing C++ in production and want a modern mental model, not legacy patterns.

📐

Tech Leads

Setting coding standards for teams and need actionable review checklists.
