Im looking for a software engineer or software developer to make me a software program

I am seeking a software engineer or developer to create a program for disabled individuals to use with their brain computer interface. The main purpose of the software program is to assist disabled individuals in performing tasks. The ideal candidate should have experience in developing software for individuals with disabilities.

Specific features and functionalities for the program have already been determined and are available in a detailed list. The preferred platform for the software program is cross-platform, compatible with both Windows and macOS. The candidate should have experience in cross-platform software development. I'm also needed an operating system for the software program if the desired candidate can do that would be great??
