General direction for the stats of my game?

My game has many levels and each level has multiple achievements. Each level the player can get a number of achievements in the form of stars and compete for the best time in around 40 levels. I can see the typical stats system used for setting this up but I'm dealing with a lot of levels. Can anyone point me in a direction on what services Kongregate offers to set this up in an organized way? You can test the game here and beat the first level to get a sense of what I'm going for https://eddygames.itch.io/hippy-skate
