The Problem
Building a conversational AI product that handles real-time chat, maintains context across sessions, and monetizes through subscriptions.
What I Built
A full-stack AI chat platform featuring:
- Real-time AI conversations with context retention across sessions
- User authentication with account management
- Stripe integration for subscription billing and payment processing
- Responsive UI with Angular, designed for both desktop and mobile
Technical Approach
- Angular frontend with a chat-style interface, handling streaming AI responses
- FastAPI backend managing conversation state, user sessions, and AI API orchestration
- Stripe webhooks for subscription lifecycle management (create, cancel, renew)
- Rate limiting and usage tracking per subscription tier
What I’d Do Differently
Would implement WebSocket connections from the start instead of polling for AI responses — reduces latency and simplifies the streaming UX.
