Cross-Platform Mobile App Build

I’m planning a brand-new mobile product and need a full-stack developer who can take it end-to-end for both iOS and Android. The core build must include secure user authentication, real-time push notifications, and a seamless in-app purchase flow tied to the respective App Store / Google Play billing systems.

I already have initial wireframes and a feature map; what’s missing is the technical muscle to turn those ideas into a polished, production-ready app. You’ll architect the back-end (any modern stack you’re comfortable with—Node, Django, Firebase, etc.), integrate it with a cross-platform framework such as Flutter or React Native, and handle store submission.

Key deliverables
• Universal iOS & Android app matching my UI/UX files
• Back-end/API with secure auth and purchase validation
• Push notification setup (APNs & FCM)
• Clean, documented source code in a Git repo
• Test builds, bug fixes, and final store approvals

If you’ve shipped apps with these exact features before, let’s talk timelines and your preferred tech stack so we can kick off right away.
