Committer

A committer is like a special person in a group project who gets to decide if any changes or additions to the project are good enough to be added in. They have the power to accept or reject the changes, just like a teacher in class who grades your homework and decides if it is correct or needs improvement. They are usually experts in the field and have been given this important responsibility because they can be trusted to make the right decisions. Think of them like the boss of the project who makes sure everything is going according to plan and only the best ideas make the cut.
