I am an experienced Python developer, for desktop app purposes, I use PyQT as my favorite tool, but depending on the customer, I can use Tkinter, wxPython. In this kworks, I will create and design for you, desktop app or software with good GUI, strong backend implementation, and good architecture for effectiveness, durability and maintainability. I will provide free maintenance and bugs fixing for the next three months after the contract ends but it depends on our clauses.
