Alex (@saguziel - AirBnB) has been making contributions and reviews for quite a long time now and I'm very happy to say he has just become an official committer and PMC member.
He has ~13 commits, most of which are to the core of Airflow, and has been active reviewing open source PRs, contributing in the recent release (e.g. fixing blocking issues), and has a strong understanding of the the core Airflow logic (he has submitted a couple of patches to remove race conditions, and security patches). Congratulations and welcome Alex! -Dan
