Saad, To add a bit to the previous excellent advice,...
I think your query may be too vague to elicit helpful responses. A better strategy might be to give a few **simple** examples of the sorts of problems that demonstrate your concerns and your code for how you approached them and reasons why you think these approaches need improvement. To maximize your chance of useful responses, keep your code snippets **short** (less than a dozen lines, say). For must of us, our eyes glaze over when confronted with pages of code that we are supposed to analyze and diagnose.
