Project description:
"I have a fully documented, API-key secured endpoint that streams live FX rates and accepts trade instructions. What I now need is a polished mobile application for both Android and iOS that consumes this API, presents the data exactly to my design spec, and lets the user place trades in real time.
Core scope
The app must fetch the latest rates from my existing API, refresh them at the interval I specify, and display them in a clean, responsive UI. From any rate tile the user should be able to tap, enter the desired amount, and submit a buy or sell order that is routed back through the same API. All authentication is handled by a simple API-key header that the app will inject into every request.
Key considerations
• Follow the visual spec I provide for typography, color and layout—pixel accuracy matters to me.
• Handle latency gracefully so the UI never freezes while a request is in flight.
• Persist the user’s key securely on device; no hard-coding.
• Deliver two store-ready builds (Google Play & App Store) plus source code and build instructions.
I am open to the framework of your choice (React Native, Flutter, Kotlin Multiplatform, or fully native) so long as it meets the performance expectations and keeps my future maintenance straightforward.
Once the project is complete I will test against my staging environment; success is a clean build, seamless authentication, accurate rate display, and a confirmed trade execution round-trip.
