Cross-Platform Startup App Development

I’m building the first version of a brand-new mobile app for my startup and need someone who can take the idea from concept to a polished release on both iOS and Android. The scope is a full cross-platform build that handles secure user authentication and a seamless payment gateway from day one. I already have the core user journeys mapped out, so you’ll be focusing on choosing the right tech stack (React Native, Flutter, Kotlin Multiplatform—whichever you’re most effective with), architecting a clean, scalable codebase, and then shepherding the project through App Store and Google Play submission. If we nail the essentials, we can always iterate later with extras like push notifications, but right now my priority is a rock-solid MVP that users can sign into, pay through, and trust. Deliverables I expect: • Production-ready iOS and Android builds, fully tested • Source code with clear comments and a brief setup README • Integration keys and credentials for auth and payments documented securely • Store-listing assets and guidance for publishing If this end-to-end assignment fits your wheelhouse, let’s talk timelines and your recommended workflow.
