Full-Stack Developer Needed | Nonprofit Health App + Admin Dashboard + Licensing System

Summary

Circle Signal™ is a nonprofit mobile-first web application for cancer patients in active treatment. Patients write one update and send it to tiered circles of support — without the exhausting weight of managing individual conversations. Recipients respond with a single emoji only. No text replies. The boundary is built into the technology.

A working interactive prototype is live at: circlesignal.netlify.app

What needs to be built:

1. Patient App

• Secure patient registration and onboarding

• Tiered contact system — Inner Circle, Support Circle, Community

• Contact import from phone (iOS and Android)

• Compose and send updates to chosen circles

• Emoji-only reaction system — NO text replies built into backend

• “I’m resting” one-tap status

• Unique private invitation links per recipient

• Spanish language support

2. Shielded SMS Relay

• Outgoing messages appear from patient’s number

• All incoming replies intercepted by server — never reach patient’s SMS inbox

• Built using Twilio with HIPAA BAA

3. Recipient Web View

• Recipients tap a private link — no download, no account needed

• Emoji reaction buttons only

• All text replies blocked at server level

4. Admin Dashboard & Licensing Control Center

• Super admin overview — active patients, licensed institutions, activity feed

• Organization manager — unique access codes, license caps, usage tracking, ON/OFF toggle per institution

• Impact reporting — exportable PDF reports for grant committees and hospital boards

• Patient management — search by ID, troubleshooting, announcements

• Role-based access control, audit logs, MFA, session timeouts

• Recommended tool: Retool or Appsmith connected to Supabase

Preferred Stack: Next.js, React, TypeScript, Supabase, Twilio, Vercel, Auth0

Requirements:

• HIPAA-adjacent architecture

• Multi-tenancy — each hospital’s data completely siloed

• Developer must be willing to sign NDA and IP Agreement

• Staging environment required
