    hey, I'm looking for a C# programmer who can convert my figma design into an object-oriented programming language. However, not only the design should be taken over, but also the logic behind the code should be written. The project involves bots that currently run as a Chrome extension. I would now like to have this written as local software. The software has to work with my Laravel backend, which is also a licensing system. Here it should be noted that the software gets a login via Discord OAuth, the licenses are queried etc. The bots should be fully integrated here. In addition, some web knowledge is required, especially in dealing with web sockets, cookies and APIs. GraphQL and a Laravel JSON API are available, which must be used.

    My project is to decrypt a .so file. This file requires decryption in order to access the contents, as it was originally a text file. The programming language of choice should be .so, as this language will give the best chance of successfully decrypting the file. The encrypted data in this file is important to me and requires the utmost precision in order to restore the information within. Accuracy and speed are of equal importance in this project, as it needs to be completed as soon as possible. If I am satisfied with the results, I can offer continued assistance with other projects.
