CivicMesh

Your neighborhood's emergency response network — connecting those who need help with those who can provide it, in real time.

Inspiration

During emergencies, neighbors often lack fast, reliable ways to communicate and coordinate. Social media is noisy, and official alerts are often delayed. CivicMesh was inspired by the need for a hyperlocal, real-time network where communities can respond together, share resources, and provide help immediately.

What it does

CivicMesh allows residents to:

  • Report emergencies (fires, floods, accidents) with photos and geolocation
  • Request or offer help for urgent needs
  • Share resources like food banks, charging stations, and shelters
  • Coordinate responses using the "On My Way" feature
  • Resolve posts with status updates and photos

How we built it

Frontend: React Native + Expo mobile app with map-based feed, photo uploads, quick post creation, and category filtering Backend: FastAPI with PostgreSQL + SQLAlchemy, secure authentication with bcrypt, REST endpoints for users, posts, and images Deployment: Render with CI/CD Team workflow: Collaborative GitHub repo with separate frontend and backend repositories

Challenges we ran into

  • Ensuring accurate geolocation across devices
  • Efficiently handling image uploads in the database
  • Keeping frontend and backend data models in sync
  • Designing an interface that works under stressful emergency scenarios

Accomplishments that we're proud of

  • Fully functional end-to-end mobile app + backend
  • Real-time community coordination features like "On My Way"
  • Clean, intuitive interface for urgent reporting
  • Scalable database design supporting geolocation, posts, and images

What we learned

  • Cross-platform mobile development with React Native
  • API design, authentication, and database modeling
  • Secure image handling and data validation
  • Effective team collaboration across frontend and backend

What's next for CivicMesh

  • JWT authentication and role-based access control
  • WebSocket-based real-time updates
  • Push notifications for urgent alerts
  • Migrate images to AWS S3 or Firebase Storage
  • Advanced map analytics and clustering
  • Admin dashboard for volunteers and responders
