Shared-Interest Matching App Development

I’m putting together a mobile app whose single, clear purpose is to match people who share specific interests. The core flow is simple: a user signs up, enters or selects their hobbies, and the platform pairs them with others who tick the same boxes. I need an end-to-end build: clean UX for profile creation and interest selection, a solid matching algorithm running on a scalable backend, and smooth iOS/Android front-end delivery (React Native or Flutter are both fine—use whichever you’re fastest with). Please factor in basic account management, notifications, and data protection best practices so we can pass the major app-store reviews without rework. An MVP that gets into TestFlight / Google Beta is the first milestone; source code, brief technical documentation, and a quick hand-off call will complete the job.
