I'm looking for a skilled app developer to build a multi-platform application (Web, iPhone, and Android) in ReactJS or React Native (what ever is most effective) that will sell QR-codes. The app will need to interface with an existing REST API and utilize the Swedish payment service "Swedbankpay". Key features of the app include: - QR-code Purchase: Users should be able to buy QR-codes through the app. - QR-code Storage: Once purchased, the app needs to store the QR-code locally for the duration of its validity. This storage is crucial as the app will primarily function offline. - Fullscreen Display: The app must allow users to display their QR-code in fullscreen mode against a black background. In terms of user data and QR-code management, the app should: - Not Use User Accounts as this simplifies the user experience. - Local Storage Only: All QR-codes must be stored locally on the device. If the phone is lost or the app is uninstalled, the purchased QR-codes will be lost. - No Recovery: There is no option for users to recover lost QR-codes. On the web, the app should: - Display QR-code Upon Purchase: Once a QR-code is purchased, it must be displayed for the user. - Screenshot Prompt: The app should prompt the user to screenshot the image or provide an email address to send the QR-code image. Ideal candidates should have: - Extensive experience with React and REST API integration. - Previous work with implementing payment services, particularly Swedbankpay, would be advantageous. - A strong understanding of offline app functionality. - Excellent skills in UX/UI design, particularly for fullscreen display features. The project requires a developer who can balance functionality with simplicity. Please provide examples of relevant past projects in your bid.

QR-Code Selling Application Development Hello, I understand you're looking to develop a multi-platform application for selling QR-codes using ReactJS or React Native. This app will need to interface with an existing REST API and integrate with Swedbankpay for payment processing. The app should enable users to purchase and store QR-codes locally and function offline, with features like fullscreen QR-code display. Eliminating user accounts simplifies the process, but we'll ensure secure local storage of QR-codes. For this project, I bring extensive experience in React and REST APIs, along with prior work in payment integration, including Swedbankpay. My focus will be on creating a user-friendly experience while ensuring offline functionality is robust. Could you please share more about the REST API setup and any specific design preferences for the app? Looking forward to your response. Regards, Muhammad Awais Do you have any specific design or UI preferences for this application? Are there any additional functionalities you envision for future updates? How do you currently handle payment processing, and are there any specific challenges? Can you provide access to the existing REST API for a detailed evaluation?

I'm excited about the opportunity to work on your QR-Code Selling Application. Building a multi-platform app that functions seamlessly offline is right up our alley. We've been crafting innovative solutions since 2000, with a team of 25+ talented folks who have delivered excellence to hundreds of clients. Integrating with REST APIs and payment services is our forte. We've had extensive experience with React.js and React Native, developing apps like an e-commerce portal and a custom affiliate system—check out our work on the Al Quran app for both Android and iOS. If you're looking for a robust solution, our experience with offline functionality will ensure the QR-codes are securely stored locally, keeping the user experience simple and effective. I noticed the requirement for Swedbankpay integration, which is a fantastic choice for your target market. To ensure a smooth transaction process, does Swedbankpay provide a sandbox environment for testing? Also, considering the local storage and non-recovery policy, do you anticipate any need for encryption or additional security measures for the stored QR-codes? While the current features are great, have you considered adding a feature where users can tag their QR-codes for easier management? It might enhance usability, especially if they purchase multiple codes. We're thrilled to discuss further details and tailor the app to your specific needs. Let's chat to finalize the scope and timeline to firm up the placeholder bid amount.

Hello, I will develop your multi-platform QR-Code selling application using either ReactJS or React Native, depending on what proves to be the most effective solution. With over 10 years of experience in web and mobile app development for both Android and iOS platforms, I am well-equipped to deliver a high-quality application that meets your needs. The application will enable users to purchase QR codes, which will be stored locally on their devices for offline access during their validity. A fullscreen display feature will allow users to showcase their QR codes against a black background for optimal visibility. To simplify the user experience, the app will not require user accounts, and all QR codes will be stored locally—meaning users will lose their purchased codes if the app is uninstalled or the device is lost, with no recovery option available. On the web, the application will display the QR code upon purchase, prompting users to take a screenshot or provide an email address to receive the QR code image. I bring extensive experience in React and REST API integration, as well as in implementing payment services like Swedbankpay. I am eager to discuss your project in further detail to ensure all requirements are comprehensively addressed. Let's connect to move forward! Thanks, Siya Technology

With extensive experience in building React and React Native applications, I am confident in delivering a solution that balances offline functionality with secure, seamless payment processing through Swedbankpay. For QR-code purchases and storage, I’ll create a streamlined process that allows users to buy and display their QR-codes with ease.
