Why Choose C++ for Your Project

  • Speed: compiled, close-to-hardware code for the fastest possible performance
  • Efficient resource use: fine control over memory and CPU, ideal for heavy workloads and devices
  • Cross-platform: one code base for Windows, macOS, Linux and embedded systems
  • Mature ecosystem: decades of proven libraries such as Boost, Qt and STL
  • Long-term stability: C++ software can run reliably for many years
  • Interoperability: works alongside .NET, Python and other languages

Our C++ Development Process

  1. Discovery: performance goals, platforms, existing code and integrations.
  2. Design: wireframes and prototypes you can review before development.
  3. Development: modern C++ in two-week sprints with code reviews and static analysis.
  4. Testing: unit tests with GoogleTest, memory checks with sanitizers and performance benchmarks.
  5. Launch: automated builds with CMake and CI/CD for every target platform.
  6. Support: updates, monitoring and new features after launch.

Our C++ Technology Stack

  • Language: C++11 to C++20, C
  • Libraries and frameworks: STL, Boost, Qt, POCO, gRPC
