3. Architecture

The application follows a microservice-oriented architecture with a clear separation of concerns.

1. Frontend: Next.js 15 with React and TypeScript.
2. Backend: API routes in Next.js for server-side logic.
3. Database: MongoDB for scalable and flexible data storage.
4. Authentication: Managed through NextAuth.js with Twitter OAuth.
5. Payments: Stripe for subscription management.
6. AI Services: User-supplied API keys for OpenAI, Claude, or Gemini.
7. Deployment: Kubernetes orchestrating Docker containers hosted on AWS.
8. Proxy: Nginx reverse proxy with SSL termination.
9. Monitoring: Sentry for error tracking, AWS CloudWatch for logs.
