Custom Mobile App Build

I want to transform my concept into a polished mobile application that runs smoothly on both iOS and Android. The core idea and initial screen flow are already outlined on paper, and now I need an experienced developer who can guide the technical decisions and then build the product from scratch.

I am open to native or cross-platform frameworks as long as the result is fast, modern, and easy to maintain. During our kick-off we will refine the roadmap together, prioritising essentials such as secure sign-in, push notifications, and—at a later phase—in-app payments. Your responsibilities will cover architecture, clean code, API integration, testing, and final publication to the App Store and Google Play.

Deliverables I will accept:
• A functional MVP installable on both platforms
• Complete, well-commented source code in a Git repository
• Simple deployment documentation and store-submission assets
• A short hand-over session showing me how to build and release the app

When you reply, please tell me which tech stack you recommend (Swift, Kotlin, Flutter, React Native, etc.) and share links to two recent apps you coded yourself. Let’s build something exceptional together.
