Junio C Hamano

Honestly, I had to pause for a second when I first saw this name — is a Git maintainer really a "celeb"? But then I thought about it and yeah, Junio C Hamano absolutely is, just in a completely different dimension than most people on this site. This is the guy who took over stewardship of Git from Linus Torvalds and has been the one holding the whole thing together for going on two decades. Every time you run a commit, a merge, a rebase — he's the reason that works the way it does. Tokyo University educated, operating almost entirely in the shadows of mailing lists and patch reviews, no public photos to speak of, no Instagram, no height measurement in any database anywhere. That's not a gap in the data, that's a personality. The man lets the code speak and I deeply respect that energy.

Junio C Hamano is a Japanese software developer and computer scientist. He studied at the University of Tokyo. He is widely recognized in the open-source engineering community and maintains a technical blog as well as a public profile on X (formerly Twitter).
