  • profiles - User profile data
  • photos - Profile photos
  • likes - Like relationships
  • conversations - Chat conversations
  • messages - Chat messages

All with indexes on common queries and foreign key constraints.

🔄 API Endpoints (21 total)

Auth (3): Register, Login, Get Current User Profiles (4): Create/Update, Get My Profile, Get Profile, Discover Photos (3): Upload, Get Info, Delete Likes (2): Like User, Get Matches Chat (3): Get Conversations, Get Messages, Send Message

Plus health check endpoint.

📈 Scalability Features

  • Horizontal pod autoscaling ready
  • Connection pooling (1-20 connections)
  • Stateless backend (any instance can handle any request)
  • Database-backed state
  • Load balancer compatible ingress
  • Configurable replicas per environment

🔐 Security Features

Implemented:

  • Password hashing (bcrypt)
  • JWT with expiration
  • CORS protection
  • SQL injection prevention (parameterized queries)
  • Protected endpoints
  • Health check separation from API

Recommended for Production:

  • Rate limiting
