I’m upgrading two existing Flutter apps and need a developer who can move quickly from UI tweaks to deeper feature work. The immediate priorities are: • Integrating Maps and Location APIs throughout the journey-tracking screens. • Hooking the apps to my custom business APIs so data flows cleanly between mobile and our back-office dashboard. • Adding a payment gateway (we’ll confirm the provider together, but the code must be written to swap providers with minimal friction). • Building and wiring reusable forms—registration, contact, feedback—so new fields can be added without touching the core logic. • Refreshing outdated widgets, polishing animations, and making sure everything compiles cleanly for the latest Android & iOS SDKs. The repository is on Git and already follows a clean-architecture layout. Expect to work in Dart, Firebase for auth/analytics, and the usual Flutter toolchain. Every pull request should include unit tests where logic is added, and I’ll test on both real devices and emulators before sign-off. Deliverables accepted when: – The new UI screens match the supplied Figma files pixel-perfectly. – Maps, location search, and live updates behave identically on Android and iOS. – All custom API endpoints respond ≤300 ms round-trip in staging. – Payment flow completes without errors in sandbox and logs are visible in the dashboard. – Forms validate client-side and server-side, persisting data to our API. If this sounds in your wheelhouse, I’m ready to give you repo access and a quick onboarding call so we can start shipping improvements right away.
