C++ FAQ
What tech leaders ask about C++ before pulling us in:
While newer languages offer great benefits, C++ remains the undisputed king of absolute performance, zero-overhead abstractions, and hardware control. It has an unparalleled, mature ecosystem (especially in Game Dev, Qt UI, and HPC), making it the optimal choice for rendering engines, high-frequency trading, and massive legacy codebases.
We strongly advocate for modern C++. For new projects, we default to C++20 or C++23 to take advantage of Concepts, Ranges, Coroutines, and Modules. For existing projects, we frequently help teams modernize from older standards (like C++98/C++11) up to C++17.
Modern C++ drastically reduces memory issues when written correctly. Our engineers strictly employ RAII (Resource Acquisition Is Initialization) and smart pointers (`std::unique_ptr`, `std::shared_ptr`). Furthermore, we integrate static analyzers (Clang-Tidy) and dynamic sanitizers (ASan, TSan) into the CI pipeline to catch any leaks or undefined behavior.
Absolutely. We are experts in the Qt Framework (Qt 5 and Qt 6) and QML. We can help you build visually stunning, highly responsive desktop applications that compile natively for Windows, macOS, and Linux from a single unified C++ codebase.
Yes. We provide senior C++ graphics programmers who have deep experience extending Unreal Engine, modifying its source code, writing custom shaders (HLSL/GLSL), and optimizing rendering pipelines using low-level APIs like DirectX 12 and Vulkan.
We utilize CMake as our primary build system generation tool, often pairing it with modern C++ package managers like Conan or vcpkg. This ensures that third-party libraries (like Boost or OpenCV) are resolved correctly across Windows, Linux, and macOS without brittle manual configurations.
Yes. Performance tuning is a core specialty. We utilize tools like Intel VTune Profiler, Linux `perf`, and Valgrind (Callgrind) to identify CPU bottlenecks, cache misses, and memory allocation overhead. We then refactor the code to improve cache locality, implement SIMD vectorization, and eliminate lock contention.
Frequently. Python is excellent for data science, but slow for execution. We often rewrite critical performance bottlenecks in C++ and expose them to Python using tools like PyBind11. This provides Python developers with native C++ execution speeds for heavy computational tasks.
