With my comprehensive understanding of React.js and React Native, I am confident in my ability to create a well-structured, optimized, and scalable React web-app for your t-shirt store. Having shipped over 50 production apps across varied industries, including e-commerce, I bring invaluable experience to this project. Significantly, over 99% of your user traffic is on mobile -one of my niches- hence ensuring a seamless mobile-user experience is second nature to me. When it comes to payment integration I'm well-versed with Razor Pay and ensuring international card and UPI acceptance are not a challenge. Furthermore, my expertise in JavaScript is complemented by the backend skills I possess in Node.js, Laravel which becomes handy to manage and tweak the simple refund pathway you require and in documenting saved orders/users data in JSON format. Let's not forget that one key area that sets me apart is my strong fraud detection skills; Given the sensitive nature payment processing online can be challenging. However, using my critical thinking faculties coupled with my product manager approach we can protect your users' information while delivering an on-point user interface product. Thus, with an MVP track record of building functional applications within tight deadlines, deploying a fully operational tested application in two weeks is not just realistic but an accomplishable undertaking I'm familiar with.

@bridgestonetech1

Hello, we can build a mobile-first React web app that lets users customize and purchase t-shirts with real-time front and back logo rendering, driven entirely from local JSON data. The flow will cover product listing, live customization, checkout, and an order-tracking page, with clean separation between UI components, state management, and API helpers so it’s easy to scale later. We’ll integrate Razorpay to support international and domestic cards, UPI, and net banking, store successful order details in a structured JSON file, and add a basic refund flow plus simple fraud checks (duplicate attempts, abnormal amounts, rapid retries) before capture. The customizer will support multiple logo sources, shapes, text styling, and instant preview on mobile with smooth performance. Fake API calls will be handled safely with loaders, retries, and error fallbacks to avoid crashes or hanging states. You’ll receive the complete Create React App codebase, sample JSON files for products and orders, and a short README explaining setup, key modules, and how to replace mock APIs with real services later. A fully testable mobile build in 2 weeks is realistic for this scope and budget. Let’s connect to confirm the timeline and kick off the build.
