I am looking for a C#, WPF, SQL, GIT developer to assist me in preparing for an upcoming exam that specifically covers the topic of C#, WPF, SQL and GIT. The level of expertise required for this exam is advanced, so I need someone who has a deep understanding of these topics. The exam is scheduled for tomorrow, 06/05/2023, so I need someone who is available to work with me immediately. The ideal candidate should have experience in C#, WPF, SQL and GIT, and be able to provide guidance and support online during exam. This project will involve online collaboration for about 90 minutes.
