I need Decompile Library(.DLL or .SO) into source code

Project Description:

I am seeking an experienced programmer or anyone who knows a thing or two about reverse engineering. I have a library that I want someone to decompile for me and provide me with working code, and not just unreadable pseudo-code. The library was prepared in C++.

I have the library compiled for Windows as a .DLL file and Linux as a .SO file. You can use whichever, or both. From what I am told the .SO has the debug info left inside of it, with the source inside being annotated. I have no plan how to extract that info. The DLL can have debug info as well.

Skills required are C++ Programming, Linux, Debugging, Software Architecture, Windows Desktop
