Add Authentication and In-App Purchases

Mobile App Development, Software Development, Mobile App Testing, Backend Development, Security, Mobile Development, API Integration, Payment Processing · I’m ready to move my existing mobile app to the next stage by introducing two key capabilities: secure email-and-password sign-up/login and a fully functioning in-app purchase flow. The current build is stable but still lacks these revenue-driving and user-management features, so I’d like to fold them in without disrupting what already works.

Scope • Implement robust user authentication based strictly on email and password, complete with validation, forgotten-password flow, and token-based session handling. • Integrate in-app purchases (consumables and/or subscriptions, depending on what the store guidelines permit) so that purchases are processed, verified, and recorded on the backend. • Refactor or patch any surrounding code that these features touch to keep performance solid and UX smooth.

Tech notes The project already uses a modern cross-platform stack, so if you’re comfortable with Firebase Auth, AWS Cognito, or a comparable service, plus native billing APIs (StoreKit / Google Play Billing), you’ll feel at home. I’ll share repo access and current architecture once we start.

Deliverables 1. Updated source code with both features fully wired in 2. Brief setup not
