I’m looking for a developer who can deliver a tiny, cross-platform (iOS and Android) mobile app that uses the Square SDK and an NFC reader to take a single, fixed donation with zero manual input from the user. Here’s exactly what the user flow should look like: • The screen shows a crisp minimalist $10 prompt. • A donor taps their contactless card or phone; the payment is processed automatically through Square. • A heart image flashes for two seconds as a thank-you, then the screen resets to the original $10 prompt. Behind the scenes I’ll need a lightweight online admin panel where I can: • Edit Square account credentials and display name. • Change the fixed donation amount without a new build. • Swap out the heart (or any other) “thank you” image on the fly. Please start your proposal with the word “TAP” so I know you’ve read the brief, and include your fixed price and delivery timeline. I’ll happily clarify Square credentials, artwork sizes, and any other integration details you need—just ask. I’m expecting someone who already understands Square NFC payment flows, app-store compliance, and the steps required to ship on both platforms.
