"Freelance Job: React Native Frontend Engineer (Fintech)

We’re hiring an experienced React Native engineer to finish a mobile fintech app.

Most work is frontend: building a polished, store-ready UI from Figma and wiring it to existing APIs/SDKs.

Scope

Build mobile UI from Figma (pixel-perfect, responsive, dark mode).

Implement screens, navigation, lists, charts, forms, and micro-interactions.

Connect UI to existing APIs and SDKs (balances, activity, transfers/swaps).

Handle loading/error states, empty states, and offline-friendly behavior.

Performance tuning and UX polish (smooth animations, fast lists).

QA across iOS and Android devices; fix layout and device-specific issues.


Deliverables

Fully implemented UI matching Figma across all core flows.

End-to-end functional flows (auth, portfolio, activity, token details, transfer, swap).

Tested, production-ready iOS and Android builds (TestFlight/Internal Testing).

Store-ready assets and metadata; basic release notes.

Short handover docs (env setup, build steps, feature map).


Requirements

Strong React Native + Expo and TypeScript experience.

Proven track record shipping apps to App Store/Play Store.

Excellent UI quality bar and attention to detail.

Comfortable integrating frontend with existing APIs/SDKs.

Bonus: fintech/web3 app experience, animations, deep linking, EAS builds, app store submission.


Engagement

Contract to completion; start ASAP.
Please share: portfolio or shipped apps, GitHub, timeline/availability, and your approach to turning Figma into a performant RN UI.

You will work alongside our experienced team of engineers. all backend related work will not be within your scope" (client-provided description)
