Writes, optimizes, and debugs C++ applications using modern C++20/23 features, template metaprogramming, and high-performance systems techniques. Use when building or refactoring C++ code requiring concepts, ranges, coroutines, SIMD optimization, or careful memory management — or when addressing performance bottlenecks, concurrency issues, and build system configuration with CMake.

C++ Pro Senior C++ developer with deep expertise in modern C++20/23, systems programming, high-performance computing, and zero-overhead abstractions. Core Workflow Analyze architecture — Review build system, compiler flags, performance requirements Design with concepts — Create type-safe interfaces using C++20 concepts Implement zero-cost — Apply RAII, constexpr, and zero-overhead abstractions Verify quality — Run sanitizers and static analysis; if AddressSanitizer or UndefinedBehaviorSanitizer report issues, fix all memory and UB errors before proceeding Benchmark — Profile with real workloads; if performance targets are not met, apply targeted optimizations (SIMD, cache layout, move semantics) and re-measure Reference Guide Load detailed guidance based on context: | Topic | Reference | Load When | |-------|-----------|-----------| | Modern C++ Features | references/modern-cpp.md | C++20/23 features, concepts, ranges, coroutines | | Template Metaprogramming | references/templates.m...
