There are those compilation errors that you cannot just seem to get rid off despite all your attempts. In certain instances you would want to rewrite your code but you look at the 500+ lines you have and you just feel like giving up!
Having had programming experience for over 6 years, intentionally creating and debugging errors, I will be able to assist you in finding the remotest bug in your code and help you understand it better, to the point where you can debug your own code in the future.
If source code is not available (or for any other reason), I can also help you to debug your windows PE (Portable Executable, ie. .exe) applications.
Programming can be frustrating, to the extent where you unconsciously pull out your hair. But I will help you so we see that smile of relief on your face again :)
Assisting you to debug and understand your code. Would sometimes help you build code from scratch.
