I’m ready to move forward with a new mobile application and I need a developer who can handle the entire build for both iOS and Android from a single codebase. I’ll walk you through the exact feature set once we connect, but the core requirement is a smooth, native-feeling experience on each platform and compliance with the latest App Store and Google Play guidelines. Here’s what I expect at a glance • A unified codebase that compiles cleanly for both platforms (React Native, Flutter, Kotlin Multiplatform, or your preferred cross-platform framework) • Pixel-perfect UI that adapts gracefully to different screen sizes and operating-system versions • Clean, well-documented source code pushed to a private repo I’ll provide • Assistance with test builds, QA fixes, and final store submission When we speak, we can flesh out user flows, data storage options, and any back-end integrations you recommend. If this is a project you can own end-to-end—from planning and design through launch—reach out here or call me directly at [Removed by Freelancer.com Admin for offsiting - please see Section 13 of our Terms and Conditions] so we can get started.

Hello, I deliver end-to-end cross‑platform apps from a single codebase that feel native on iOS and Android, comply with current store policies, and ship with clean, documented code. What I provide: Unified codebase: Flutter or React Native (Kotlin Multiplatform if preferred), shared business logic, native bridges where needed, and reliable build pipelines. Pixel‑perfect UI: Responsive layouts, adaptive components, accessibility, and smooth performance across devices and OS versions. Store compliance: Proper SDK targets, privacy disclosures, permission rationale, and readiness for App Store and Google Play submission. Workflow: Private repo access, readable documentation, frequent test builds, and rapid QA fixes through to launch. Approach: Plan: Clarify user flows, data models, and offline/real‑time needs; choose framework aligned with long‑term maintenance. Build: Implement core navigation, state management, and APIs with modular architecture and test coverage. Polish: Performance passes, analytics/crash reporting, localization, and accessibility checks. Launch: Prepare store assets, submission materials, and address review feedback. Ready to discuss the feature set, storage options, and back‑end integrations to own the project end‑to‑end. Best regards, Vicky Keswani
