I have no desire to poo-poo your contributions, but with 30 commits over a 2 year period and very sporadic engagement on the issue tracker, "contributor" seems completely fair but "maintainer" seems a bit much. Maintainers are the people who are involved reasonably consistently for the long term, and also do the un-sexy work of tracking down the (sometimes difficult) bugs people report, triage the (unclear) issues people report, deal with generic support requests, and all of that.
