QR-Driven Event Photo Sharing App

Project Scope: Event-Based Photo Sharing Platform (Web + Mobile App)

We are looking to develop a web application and mobile-compatible platform that enables users to create private, event-based photo galleries with QR-code-driven uploads.

Core Functional Requirements

1. Event Creation & Management
• Users must be able to create an event through a dashboard.
• Each event should include:
• Event name
• Date/time (optional)
• Unique event ID
• Upon creation, the system must generate a unique, secure QR code associated with that event.

⸻

2. QR Code Photo Upload System
• The generated QR code should:
• Redirect users to a dedicated upload page tied to the specific event.
• Guests (non-authenticated users) must be able to:
• Upload photos directly from their device (mobile-first experience).
• Upload multiple images with minimal friction (no login required).
• The upload system should support:
• Common formats (JPEG, PNG, HEIC)
• Automatic image compression/optimization

⸻

3. Private Event Gallery
• Each event must have a secure, private gallery:
• Accessible only by the event creator (authenticated user).
• Guests cannot view uploaded content, only upload.
• The gallery should include:
• Grid view of images
• Download functionality (single + bulk)
• Optional: sorting, filtering, and favorites

⸻

4. Authentication & User Accounts
• Users must be able to:
• Register / log in securely
• Manage multiple events from a dashboard
• Authentication should support:
• Email/password (minimum)
• Optional: OAuth (Google/Apple)

⸻

5. Payment Integration
• Event creation or gallery access must be gated behind payment.
• Integrate a payment processor (e.g., Stripe) to:
• Charge per event or subscription-based model
• Features:
• Payment confirmation before QR code activation
• Basic billing history for users

⸻

6. Security & Privacy
• Ensure:
• Event galleries are private and access-controlled
• Upload endpoints are protected against abuse (rate limiting, file validation)
• Use:
• Signed URLs or token-based access for uploads
• Encrypted storage (or secure cloud storage like AWS S3 / Firebase Storage)

⸻

Suggested Tech Stack (Open to Recommendations)
• Frontend: React / Next.js (responsive, mobile-first)
• Backend: Node.js (Express) or Firebase / Supabase
• Database: PostgreSQL or NoSQL (Firestore)
• Storage: AWS S3 / Cloud Storage
• QR Code Generation: Server-side library (dynamic per event)
• Payments: Stripe API

User Flow Summary
1. User signs up / logs in
2. User creates an event
3. System generates a QR code
4. User shares QR code with guests
5. Guests scan QR → upload photos
6. Photos are stored and linked to that event
7. Only the event creator can access and download the gallery

Goal / Use Case

This platform is designed for events (weddings, birthdays, parties, corporate events) where attendees can easily contribute photos in real-time via QR code, while keeping all content privately accessible to the host. Show More
