Hi, I’m experienced with Flutter, mobile architectures, and backend API integrations. Migrating from native Android (Java/Kotlin) to FlutterFlow while keeping the PHP backend intact is a task that requires both mobile knowledge and API understanding — which I work with regularly. I can ensure: – Proper API integration with your existing backend – Clean UI logic inside FlutterFlow – Functional parity with your current app – Structured and maintainable project setup I focus on stability and correctness, not just visual replication. Let’s make your transition smooth and future-proof.

I understand exactly what this requires: rebuilding an existing Java/Kotlin Android application into FlutterFlow while keeping your PHP 5.6 REST APIs unchanged. This is a controlled migration, not experimentation. UI flows, API bindings, auth, state handling, and edge cases must match the current production behavior module-by-module. I have hands-on experience with Android (Java/Kotlin), Flutter, and FlutterFlow, including API-driven apps where the backend cannot be touched. My approach is to map each module’s screens, API contracts, and logic first, then rebuild them cleanly in FlutterFlow with custom actions where needed. Nothing is guessed. Nothing is improvised. Confidentiality is non-negotiable. I’m comfortable signing an NDA and treating the source as sealed material. Code will not be reused, shared, or referenced elsewhere. Deliverables include a fully functional FlutterFlow project, commented custom logic, a concise architecture summary, and successful deployment to both Play Store and App Store.
