Howdy!
There's some significant overlap between freedom tech and resilient communities. These communities come in all shapes and sizes; and a lot of them are intentionally very low profile. Some of my own interests include microhydropower and 'Terminating Building Societies'.
You have a lot of very relevant experience to offer. I think there's a need to build clusters of professionals who are willing and able to contribute to new and 'rebooted' community projects, and I certainly think that could be done in Nostr.
Maybe have a play with Figma or Penpot to imagine and share what the UX / UI would look like.
