You need to create a program "Calculator" on Windows (Windows Forms / C#) that replicates the functionality of a classic calculator with a visual interface
The program allows performing basic arithmetic operations: addition, subtraction, multiplication, division, percentages, sign change, reset, etc.
The goal is to make a simple, fast, and stable calculator with support for keyboard, mouse, and dark interface.
The application is suitable for:
PC users looking for a simple offline calculation program.
Companies wanting a branded calculator in their style (logo/brand can be added).
Students or teachers as a demonstration example for learning the basics of programming in C#.

My name is Oleksandr, I am a developer with experience creating desktop applications in C# using Windows Forms. I am ready to implement a simple, stable calculator with a classic visual interface for you. The program will allow basic calculations, work with both mouse and keyboard, support dark theme, and also include the option to add a company logo or style it with corporate colors.
I focus on speed, convenience, and clean code, so I can guarantee a clear project structure, comments in the code, and full delivery of both the executable file and source materials. I can start work immediately after clarifying the details and complete it in the shortest possible time. If needed, I can add a demonstration video or a short README with usage instructions.
I look forward to collaborating!
