Vi0/CR/AR

This project first started when I was still in highschool. The main goal was to create a platform with recorded daily highscores of an MMO and provide statistics on this data. "Vi0" is the name of the clan I was a member of.

Several years of historic data are still available on the site.

The site was first written in PHP and has now evolved into an React SPA/PWA.
