I need a robust desktop application written in C or C++ from the ground up. The job spans the full software-development cycle: designing the architecture, coding the core logic, creating a clean GUI, and packaging an installer ready for end-users. Modern C++ practices, strong command of data structures, and solid problem-solving skills are essential because the application will manipulate sizeable local data sets and present real-time results on screen. While the detailed functional specification will follow under NDA, you can picture a medium-scale utility that loads files, performs in-memory analysis, and visualises outcomes in an intuitive interface. Cross-platform support is a plus, but Windows 64-bit compatibility is mandatory. Deliverables • Entire, well-commented C/C++ source tree (preferably organised with CMake) • Compiled desktop binaries and an installer for Windows; extra Linux/macOS builds welcome • Brief build notes and a concise user guide (PDF or Markdown) Let me know which frameworks or libraries (Qt, wxWidgets, Win32, SDL, etc.) you prefer, any third-party dependencies you foresee, and an estimated timeline so I can align milestones accordingly.
