This project was written from scratch using zero frameworks and only my own libraries. Website had basic functionality so I've seen no use for them. There was authorization system using Google and Facebook for login, administration panel for news and events and more. After long year project was completed with loading times 2-10ms (0.01 second) with 0% CPU/RAM usage and ability to handle huge amounts of traffic (which was needed as the website had daily from 20 to 50 thousand visitors).
