I need a straightforward B2C mobile-recharge application built for both iOS and Android. The core scope is limited to three must-have features: • User registration and secure login • Integrated payment gateway for quick top-ups • Clean transaction history that users can filter and review Code should be production-ready, tested on current OS versions, and handed over with all necessary keys and documentation to make future updates simple. Please tell me about similar recharge, fintech, or wallet projects you have completed so I can gauge your experience with payment flows, security, and multi-platform deployment. Looking forward to collaborating with someone who can turn this into a polished, store-ready release without unnecessary delays.
