451 USD Mobile Frontend Developer (Flutter or React Native) — for a duration of 1-1.5 months

Payments: SEPA / Faster Payments / SWIFT (incoming/outgoing), payment by IBAN, contacts + templates.
Currency exchange: pair "I pay → Receive", rate fixed for 30 minutes, "0% fee" up to the limit, thereafter — spread display.
Cards: virtual (issue, freeze/unfreeze, PIN/CVV), ordering physical (address/delivery, KYC-gate).
Tokenization in Apple Pay / Google Pay (via respective SDKs, with backend support).
Statements: export PDF/CSV.
Tariff plans and upsell: Free / €10 / €20, FX/transfer limits, upgrade in 2 clicks.
Notifications: push (FCM/APNs), in-app.
Support chat and premium agent 24/7: built-in messenger.
Settings/security: 2FA, limits, devices, log out everywhere.

Connect SDK for KYC/liveness (like Sumsub/Veriff/Ondato) — integrate screens + handle states.
Integrate Apple Pay / Google Pay (set up client-side tokenization).
Connect backend API (NestJS) and handle states: loading/empty/error/offline/timeout/retry.
Cover main events with analytics (screens, submits, failures).

Commercial experience with forms/validations/OTP, complex navigation flows.
Very neat UI: animations, gesture navigation, accessibility, localization (i18n), RTL — as a plus.
