I need a new iOS application built for Keshav Tech that will boost brand engagement and give our users a smooth, secure experience on their iPhone or iPad. The core features are already clear: • User authentication – create, sign-in, and manage accounts with standard email or social login. • Payment processing – in-app purchases or Apple Pay/Stripe so users can complete transactions without leaving the app. • Push notifications – time-sensitive, opt-in alerts to keep our audience connected to new content and offers. I’m looking for a developer who can turn these requirements into a functional, polished prototype and then refine it into an App Store–ready build. Clean, maintainable Swift code, Xcode project files, and concise setup documentation are key acceptance criteria. You’ll collaborate directly with me on UI flow, wireframes, and any backend hooks, then handle TestFlight distribution for final testing. If you have proven experience shipping apps with these exact capabilities, I’d love to see your portfolio and discuss timelines.
