Paid on delivery
I need a lean, working prototype of a delivery app focused on one core feature: secure payment integration. The goal is to let users log in, place an order, and pay on the spot—nothing more for now. Key elements I’m after: • User login screen tied to a simple database (email + password is fine). • Checkout flow that accepts Credit/Debit cards and Bank transfers, using any well-documented gateway or SDK you prefer. • Clean, functional screens for cart review and payment confirmation. • A straightforward admin panel or endpoint so I can see incoming transactions. I’m not looking for full order tracking or push notifications yet; this is the minimal version to validate payments. A lightweight tech stack such as React Native, Flutter, or similar is fine, as long as setup instructions and runnable source code are included. Deliverables: 1. Buildable source project with clear README. 2. Tested APK/IPA or emulator build showing the payment flow end to end. 3. Brief hand-off call or document outlining how to plug in my own gateway keys. If you can turn around a clean, no-frills solution quickly, let’s get started.

Hi I can build a lean delivery app prototype focused on secure login, cart review, checkout, payment confirmation, and basic transaction visibility. The main technical challenge is keeping the app minimal while still making the payment flow reliable, secure, and easy to replace later with your own gateway credentials. I can solve this using React Native or Flutter, simple email/password authentication, a lightweight backend, database transaction records, Stripe or another well-documented payment SDK, and a basic admin panel or API endpoint for viewing payments. The prototype will include clean screens for login, order/cart review, card or bank-transfer checkout, and payment success/failure confirmation. I’ll keep the code organized and documented so future delivery features like tracking, push notifications, driver assignment, and order history can be added later. The final handoff will include runnable source code, setup instructions, a tested build, and clear notes for replacing test gateway keys with your own. Thanks, Hercules

Hi, I can build your lean delivery app prototype with a secure, end-to-end payment flow quickly and cleanly. With 10+ years of experience in mobile and full-stack development (React Native, Flutter, Node.js), I’ve implemented payment systems and MVP apps focused on fast validation. Approach: I’ll use React Native for a lightweight cross-platform app and Node.js backend for handling auth and transactions. For payments, I recommend Stripe (cards) + bank transfer support (via Stripe or alternative like Razorpay depending on region). What you’ll get: • Simple login system (email/password with secure auth) • Cart → checkout → payment → confirmation flow • Integrated payment gateway (test + live-ready setup) • Basic admin endpoint/dashboard to view transactions • Clean, minimal UI focused on functionality Everything will be well-structured, documented, and easy to extend later. Deliverables include full source code, working APK/IPA (or emulator build), README, and guidance to plug in your own payment keys. Timeline: 3–5 days for complete working prototype. Ready to start immediately and deliver fast. Best regards.

Hi, I can build a lean delivery app prototype focused purely on secure payments, with a clean flow from login to checkout and transaction confirmation. I’ve worked on payment-first MVPs where speed, clarity, and reliability are the priority. My approach is to use Flutter or React Native for fast cross-platform delivery, with a lightweight backend (Node or Firebase) to handle authentication and transaction logging. I’ll implement a simple email/password login, cart review screen, and integrate a trusted payment gateway like Stripe or similar for card payments, plus a bank transfer option where applicable. The app will include a clean confirmation flow and a basic admin endpoint or dashboard to view transactions in real time. Everything will be structured clearly so you can plug in your own API keys and extend later. You’ll receive a working build, full source code, and a clear setup guide to run and modify the app. Best, Justin

Hello, I see you're aiming for a lean delivery app prototype with the sole focus on secure payments and minimal screens. Keeping the scope tight around login, checkout, and gateway integration is the right approach for validating your flow without overhead. I’ve delivered similar React Native and Flutter builds where I implemented Stripe and Paystack payments, producing clean end‑to‑end payment confirmations and lightweight admin endpoints so clients could monitor transactions easily. The real challenge here is ensuring the payment SDK is integrated in a way that remains modular, so you can later expand features, order tracking, notifications, or multi‑merchant logic, without reworking the core checkout pipeline. I’ll set up a simple email/password auth system, build the cart and confirmation screens, and integrate a documented gateway with test and live modes. I’ll also create a small admin endpoint to list transactions and include a clear README plus build instructions. Before finalizing, I need clarity on which gateway you intend to use and whether you require sandbox keys included. Thanks, John allen.
