- Maintain existing OAuth authentication for user access
- Complete the integration within a 3-hour timeframe

Ideal Skills and Experience:
- Strong proficiency in React, Node.js, and TypeScript
- Experience with Stripe API integration for subscriptions
- Familiarity with OAuth authentication methods
- Ability to work efficiently under tight deadlines

Please ensure you have the necessary expertise and availability to complete this task promptly.
