Mobile Coffee Ordering App Build

@infowider11

Hello, How are you? **** Custom Closed-Loop Digital Wallet App Development **** I will develop a secure, scalable closed-loop digital wallet application enabling users to preload funds, pay in-store via dynamic QR codes, earn rewards, and track transactions—built with Flutter (iOS & Android) and a secure backend such as Firebase or AWS with Stripe integration for PCI-compliant top-ups. The MVP will include wallet balance management, real-time transaction history, loyalty logic (spend-to-earn), menu display, and a web-based admin panel for monitoring users, transactions, rewards campaigns, and reporting—ensuring no sensitive payment data is stored locally. Let’s chat.. Thanks

@leadconcept

Greetings, Do you prefer the QR payments to be fully offline-capable at the POS, or is real-time backend validation acceptable for MVP? Our understanding is that you need a cross-platform mobile wallet app with secure top-up, QR-based in-store payments, loyalty rewards, transaction history, menu display, and a scalable architecture for future in-app ordering, alongside an admin panel for monitoring users, balances, rewards, and menus. Our team has extensive experience building fintech and wallet systems, integrating Stripe and other PCI-compliant gateways, developing real-time backend architectures with Firebase or AWS, and delivering clean, secure, and store-ready mobile apps.

Hello, this is exactly the kind of secure, transaction-focused mobile system I specialize in building. A closed-loop wallet requires strong backend controls, not just QR payments. Proposed Tech Stack • Mobile: Flutter for unified iOS + Android performance • Backend: Node.js (NestJS) or Firebase Functions • Database: PostgreSQL or Firestore (depending on transaction volume) • Payments: Stripe or iyzico with PCI-compliant tokenization • QR System: Dynamic, short-lived encrypted QR tokens • Hosting: AWS or Firebase with environment separation Core Architecture • Wallet ledger model (no balance stored directly, all transactions recorded) • Atomic transaction handling to prevent double-spend • Reward engine as modular rule-based service • Real-time balance updates • Admin web dashboard with campaign management • Secure webhook handling for payment confirmations • No sensitive card data stored locally Experience I’ve worked on fintech-style flows including secure payment integrations, wallet logic, and role-based admin dashboards. Estimated Timeline: 10-14 weeks for MVP Budget Range: Mid five-figure depending on reporting depth and compliance requirements Deliverables include production-ready builds, full source code, documentation, and post-launch stabilization support. Let’s open the chat. I can outline the wallet transaction model and QR security flow before we proceed. Best, Jenifer

Hi there, I can build your closed-loop wallet app where users can sign up, add money through Stripe, check their balance, pay in-store using QR, and earn rewards as they spend — with a solid backend behind it. I will ensure funds go directly to your business account through Stripe while the app maintains a secure internal wallet ledger with accurate balance updates and safe transaction handling. I will also implement a smooth QR payment flow for fast and reliable in-store payments. Along with that, I will also build an admin panel where you can manage users, monitor balances and transactions, adjust rewards, update menu items, and view reports — all connected to the same system. I would request to connect once to discuss the tech stack and few more points. Ping me once you are available. Thanks, Rahul A.

@deepbansal1111

Hello I have read your requirement to build a custom closed-loop digital wallet application with QR-based in-store payments and rewards logic. I can do that, and I have 8 years of experience in mobile app designing and development with a backend. I have developed more than 200+ mobile apps with the backend till now, including fintech-style wallet systems, Stripe integrations, and secure transaction-based architectures. Your project requires much more than a standard app build. A wallet system must be designed with a proper ledger structure, server-side balance validation, atomic transactions, and secure QR token generation to prevent misuse. I would build this using Flutter for a smooth cross-platform experience on iOS and Android, combined with a scalable backend such as Firebase with Cloud Functions or AWS with Node.js/NestJS depending on your scaling expectations. All payment processing would be handled through Stripe or a PCI-compliant provider, ensuring that no sensitive payment data is stored locally. The wallet balance logic, rewards calculation, and QR validation would run securely on the server side. The admin panel would be developed as a web dashboard connected to the same backend, allowing you to monitor users, manage campaigns, adjust reward rules, and access reporting in real time. The architecture will be designed so that adding in-app ordering in Phase 2 will not require rebuilding the system.

@corpmember29

Hello!! " Mobile Coffee Ordering App "{{{ I HAVE CREATED SIMILAR APPS BEFORE AND I CAN SHOW YOU }}}} I have carefully reviewed your requirement for a closed-loop wallet-based coffee ordering app. With 10+ years of experience in fintech-enabled mobile applications, wallet systems, and secure payment integrations, I clearly understand the importance of transaction integrity, scalability, and PCI-compliant architecture. Proposed Tech Stack: Flutter (single codebase for iOS & Android), Firebase or AWS (scalable backend with secure role-based access), Stripe integration with tokenization (no sensitive data stored locally), and dynamic QR generation with server-side validation for in-store payments. Approach: Phase 1 (MVP): Wallet creation, top-up, QR-based payments, transaction logs, loyalty engine (spend-to-earn logic), and admin dashboard for monitoring balances, transactions, reward rules, and menu management. Architecture will be modular to easily extend into Phase 2 (in-app ordering) without restructuring the core wallet logic. Security will include encrypted communication, server-validated QR tokens, atomic wallet transactions, and proper audit trails. I WILL PROVIDE 2 YEAR FREE ONGOING SUPPORT AND COMPLETE SOURCE CODE, WE WILL WORK WITH AGILE METHODOLOGY AND WILL GIVE YOU ASSISTANCE FROM ZERO TO PUBLISHING ON STORES. I am confident my experience aligns with your long-term partnership vision. I eagerly await your positive response. Thanks.

Hi there, I will build the cross-platform app with the closed-loop wallet, Stripe top-up, QR-based in-store payment, spend-to-earn rewards, transaction history, and menu display, plus the admin panel for users, transactions, reward campaigns, and menu items. Architecture will be ready for in-app ordering in the next phase. For the QR payment flow, I will generate single-use, time-limited tokens tied to the transaction amount. Each QR expires after a short window so it cannot be screenshotted and reused, and the server validates the token once before marking it spent. This prevents replay attacks without adding friction at the register. Questions: 1) Are you set on Stripe, or is iyzico still being considered? 2) Will the QR be scanned by the customer or by the cashier? Feel free to reach out if you want to go over anything. Kamran

@usamae

Built a couple of closed-loop wallet apps before so this setup - preload money, QR payment, rewards - is territory I know well. I'd start with the wallet engine and iyzico integration, then the QR generation and scanning flow, then layer on rewards. The key is keeping the architecture modular from day 1 so the ordering phase you mentioned drops in cleanly without a rewrite. Using Flutter for cross-platform, with a clean REST API backend. Portfolio includes fintech and marketplace apps - happy to share relevant work. - Usama
