Freetime Projects


This is a web application written in PHP it’s unfinished. It contains a registration and betting-system with virtual currency on matches of the video game “League of Legends”.

This is an application I currently have halted development on, due to a third-party API, which the application heavily relies on, that is no longer available. It is used to track your progress in the computer game “League of Legends” and saves said progress to a local database. I developed that application in my free time. It’s completely written in Java.
