Need Help in advancing my knowledge base

@lazyme114 ,

There are many tools, videos and tutorials about optimizing and refactoring code. Check youtube & Google. If I were to put it into words the best way I could explain it to you is to give an example. Take one of your older projects and review the code. Based on your knowledge now would you have programmed it the same way? If not, how would you have programmed it differently? Were there any bottle necks in your old program? Based on what you know now how would you have fixed the bottle neck now? You could also ask a more senior developer that you may know if they can look at your code and give you suggestions on how to improve it.
