Project description:
"I need to extend an existing e-commerce platform with several cross-border features and a cleaner UI refresh.

Primary work revolves around Airwallex: the site must call [login to view URL] endpoints to enable bank-transfer payouts and collections, with a simple switch in the admin panel so I can turn the gateway on or off per store.

Scope of changes
• Backend configuration: a new “Payment & Currency” section where I can map keys, view logs, and decide which currencies each merchant may offer.
• Product listing: merchants should add any currency code they need; the front end then shows buyers a drop-down so they can pay in their preferred currency at checkout.
• Corporate KYC: expand the qualification form with 3–5 upload slots for both sides of an ID card. Images must be stored and retrievable in the current file system we use.
• Deposit control: introduce a configurable spending cap that checks the remaining balance before each order and blocks anything over the limit.
• Overseas sign-up flow: add SMS verification for non-domestic numbers; success returns the same token our local flow already saves.
• UI improvement: while touching these modules, refresh the screens for a smoother look and feel (my priority is clarity, not heavy redesign).

Acceptance
1. Airwallex sandbox demo shows full bank-transfer cycle (create payment intent, confirm, capture, refund).
2. Multi-currency prices appear correctly and settle back into the admin in the chosen currency.
3. File uploads pass size/type validation and display thumbnails in the review page.
4. Deposit cap blocks over-limit orders and logs the attempt.
5. International SMS delivers and validates within the existing user table.
6. Code is clean, commented, and pushed to our Git repository with a short README for setup.

I’ll be available to provide existing source access, current DB schema, and quick feedback as you progress." (client-provided description)
