Rewrite a DirectX9 Shadow System (I need correct shadows) -- 2

I am looking for a skilled developer to rewrite my DirectX9 Shadow System. The current system is causing issues with shadow accuracy during gameplay. Specifically, the shadows are projecting also backwards with the current implementation. I am looking for correct, realistic shadow system that provides clear and accurate shadows for my game. The project requires experience in C++ programming language and DirectX9/HLSL.

Skills required:
- Strong experience in C++ programming language
- Proficiency in DirectX9
- Experience with shadow systems
- Attention to detail
- Ability to create accurate and realistic shadows for gameplay
