RWCBM
A private members' network, web and mobile
A private hall where members list their companies, post what they are building, and ask each other for help. Invite-only, with a privacy model designed around the fact that a business phone number and a personal one are not the same thing.

The problem
A members' directory is easy. A members' directory that people will actually put their real contact details into is not. The group needed somewhere private, credible-looking, and specific enough that a member could ask for help without publishing their cell number to the internet.
What got built
Next.js on Clerk and Vercel Postgres, with a deliberate privacy layer: business contact details are visible to signed-in members, personal ones stay hidden behind per-field share toggles, and every profile carries a contact form that routes mail through Resend so an address is never exposed in the UI. A React Native companion app shares the same Clerk instance, so members sign up on the web and log in on the phone.
Details worth naming
- Invite-only sign-up with per-field privacy toggles separating business contact details from personal ones.
- Business directory and a community request board: post a need, mark it fulfilled, respond by email without exposing addresses.
- Member directory rendered as a searchable Mapbox map of US locations alongside profile cards.
- Admin console for category moderation, with user-submitted categories held for review before they enter the taxonomy.
- Upstash rate limiting on write paths and a Node test suite covering search, enrichment, notifications, and permissions.
