Whilst I wouldn't class myself a full-time contributor, I have tried to contribute here and there.

With the Github access I suspect my main contribution initially will be to help garden issues (close them where I currently cannot, e.g. #24573, relabel etc)

With the Gerrit access I'd be looking to restart trybots (for example in the CL https://go-review.googlesource.com/c/go/+/103415)

Thanks for considering my request.
