Apply to become a maintainer (#30884)

Hello! After contributing for some time I am interested in taking a more
involved role as a maintainer. When time allows it, I plan to perform
code reviews, continue resolving/triaging issues, and engage with the
community to see if I can offer any useful insights. My current
interests are in backend work, but I plan to study the web frontend
architecture to see if I can contribute there as well.

Thanks for this awesome project. I hope I can both learn and contribute
to its continued success!
