🏢 About the Project

We are looking for a Backend Developer for a short-term contract project in the mental health / wellness domain.

• authentication and RBAC
• patient access controls
• journals and check-ins
• AI companion
• voice transcription
• prescriptions
• care plans
• wellness
• billing and other modules

This is a well-structured contract project with a clearly defined scope, documentation, and expected outcomes for each task.

• Complete the pre-session brief worker handler:
  • job scheduling is already in place
  • current handler only contains placeholder logging
  • implement actual brief generation and delivery logic
• Fix the USDA_API_KEY configuration:
  • wellness route currently falls back to DEMO_KEY
  • implement proper secrets / environment management
  • remove fallback behavior
• Collaborate with the frontend / clinician portal developer:
  • define and document backend endpoints for:
    • transcript workflows
