I will create custom desktop applications

Please provide a detailed description of your project including the purpose of the application, desired features, target platform (Windows, Linux, macOS), any specific frameworks or libraries you prefer, and design references if available. The more details you provide the faster I can deliver.

Yes absolutely. Every package includes full source code with detailed comments. The Premium package also includes comprehensive documentation covering installation, usage, and code architecture. All code is clean, well-structured, and follows best practices.

I write unit tests, conduct code reviews, use static analyzers (Clang-Tidy, PVS-Studio), and profile to identify bottlenecks.

Yes, I do. I perform profiling, identify bottlenecks, optimize algorithms and memory usage, and modernize code to comply with current standards. I eliminate memory leaks and improve overall performance.

I support Windows, Linux, and macOS. I work with Qt, SDL, ImGUI, OpenGL, and Vulkan. For backend I use C++ with Python integration. I can also build console applications, GUI desktop apps, graphics software, and high-load APIs.

Yes. I have extensive experience integrating with SQLite, PostgreSQL, and MySQL databases. I also work with REST APIs, WebSockets, and various third-party services. Just let me know what you need and I will handle the integration.
