The Meta team is responsible for maintaining and managing WordPress.org websites. Our work is mostly done on the meta trac. If you see a bug, file a ticket!
On your profile, badges are added based on your contributions to the WordPress project. There are two kinds of badges: contributor and team. The contributor badges are generally assigned to anyone who has contributed to a particular team. Meanwhile, the team badges are given to those who are active on their team. Each team can set its own criteria for who should get each badge. When possible, the meta team will automate badge assignment.
Here are the list of badges that currently exist:
