Hello, I can polish your app’s backend to get it MVP-ready, handling authentication (Google, Apple ID, Facebook), in-app support ticketing, a points/leaderboard system, app settings functionality, and general touch-ups. Using Node.js, Express, Firebase, and React Native with TypeScript, I’ll ensure smooth authentication, secure APIs, and reliable database integration so your app feels complete and stable. Questions: – Do you already have Firebase configured for authentication, or should I set up the providers from scratch? – Should the support ticket system connect to an external platform (e.g., Zendesk) or remain in-app only? Looking forward to potentially working together on this project. Thanks and Best regards, Kamran
