🏢 About the Project

We are looking for an Expo / React Native Developer for a short-term contract project in the mental health / wellness domain.

The project includes two frontends:

• 📱 Mobile App — Expo / React Native
• 💻 Clinician Portal — React + Vite

The backend (Express / TypeScript / Prisma) has already been implemented and is operational for core functionality, including authentication, RBAC, patient data, logs, check-ins, the AI companion, and other key modules. The main goal is to connect the existing frontend parts to the real backend APIs instead of static mock data.

This is not a role focused on building new architecture or creating new screens. We are looking for a developer who can quickly dive into an existing codebase and complete integration tasks efficiently.

💼 Responsibilities

📱 Mobile App (React Native / Expo)

• Replace mock data in:

  • CarePlanScreen.js
  • MedicationsScreen.js
  • AppointmentsScreen.js
  • SafetyPlanScreen.js

  with real API calls to existing backend endpoints

• Fix the push notification registration flow:
  • the mobile app currently posts to /device-tokens
  • the backend route is mounted at /api/v1/device-tokens

• Remove the hardcoded CloudFront URL from api.js

  and implement environment-based switching (dev / staging / prod)

• Clean up the Journal screen:
  • remove remaining mock historical entries
  • ensure all data flows through the backend journalService
• Remove the seed patient fallback and mock response path from the companion chat (ai.js) so all authenticated sessions use the real backend

💻 Clinician Portal (React / Vite)

• Integrate the session transcript viewer with the real backend transcript endpoint

• Connect:

  • SOAP note generation
  • ICD-10 coding
  • Action items

  to the corresponding backend API routes

• Integrate the pre-visit summary with the backend endpoint

  (currently uses hardcoded mock data in clinician.jsx)
