Full software lifecycle support. Requirements gathering, design, development, verification, implementation, and support. Desktop application for x86, AMD 64, and various Arm platforms running Windows, Linux, and macOS. Requirements and models are in Sparx Enterprise Architect. Source code projects are in Qt Creator, Eclipse, NetBeans, and MS Visual Studio. Possible tech stacks: C++/Qt, C++/MFC, C++/Win API, Java 2 SE/Swing, C#/WPF.NET, C#/WinForms.NET. I often use PostgreSQL as a DBMS. If audio, video, or image processing is required, I can use hardware acceleration and GPUs, as well as H.264 decoders and encoders. OpenCL is also possible. I use Key Cloak as a library for authentication and authorization. For interaction with MS Office, I use VSTO.NET or corresponding Active X components. This service is an activated stage of the project work, when there is something to deliver.

For the paid service, you receive implemented functionality comparable in complexity to 500 lines of Java or C# code.

These 500 lines include:
- Implementation of a consistent layout for dialog forms, if any
- Processing of command line parameters
- Developing build environments for all relevant platforms and build options
- Implementation of the necessary interaction when working with a database
- Implementation of the required integration with third-party tools via API.

You will also receive a runtime environment where you can test your work (either as a virtual machine image or by providing remote access to existing ones). Along with the code and its build, you will be able to track the completed work in relation to tasks in the corresponding task management system, where source code changes are linked to task definitions.
