Hi @redcamel, welcome.

I'm unable to find a positive answer here. There is a /profile page. From reading the source code (about/html/edit.js), it looks like name, avatar, and publicWebHosting can be updated, but not description.
I don't see a way to publish a raw JSON message either (i.e. to publish the "about" message with "description" field); so maybe this must be done using another client/app (e.g CLI).
