Documentation

README

Excerpt

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
