Android & iOS App Development

I’m ready to move an idea from concept to fully-released mobile app and need an experienced developer who can deliver clean, production-ready builds for both Android (Google Play) and iOS (App Store).

Here is what I have in mind:
• One shared code-base (Flutter, React Native or similar) or two native builds—whichever you recommend for long-term maintainability.
• End-to-end support, from initial architecture and UI implementation through testing, store submission and first-release monitoring.
• Clear, well-commented source code handed over in a private repository, along with basic setup documentation so I can spin up the project locally.

Acceptance will be based on:
1. Stable, crash-free installs on current Android and iOS versions.
2. Successful listing and availability in both stores under my developer accounts.
3. A short knowledge-transfer session (recorded video or live call) walking me through build, signing and deployment steps.

If this scope fits your expertise, please share relevant portfolio links, your preferred tech stack and an estimated timeline for a first MVP.
