Hello, I have 10 years of experience developing scalable ecommerce and marketplace applications for web and mobile platforms. For your project, I recommend React Native for the iOS and Android apps, with Node.js, REST APIs, and PostgreSQL providing a scalable backend architecture. I would implement secure account management, social login, profiles, wish-lists, Indian payment gateway integration including UPI and wallets, product reviews with ratings and photos, and moderation workflows. The architecture would be designed around clean modules, secure authentication, optimized APIs and database queries, responsive UI, and maintainable code so the platform can scale as the catalogue and user base grow. I can also provide relevant ecommerce project examples. I’d be glad to discuss the expected scale, payment providers, and development milestones. Best regards

Hello, Building an Amazon/Flipkart-level experience starts with a scalable foundation—not just a polished shopping interface. Questions: 1. Which Indian payment provider do you prefer for UPI, cards and wallets, or should I recommend the best option? 2. Do you have a target catalogue size and expected initial monthly users so I can design the architecture accordingly? I can develop the iOS and Android apps using Flutter with a scalable Node.js/NestJS backend, PostgreSQL, Redis caching and cloud-ready infrastructure. With 17+ years of development experience, I can build the architecture around performance, security and future growth while keeping the codebase clean and maintainable. • Secure authentication, social login, wishlist and scalable product/catalogue APIs • Indian payment integration with reliable transaction and order handling • Review/photo moderation, optimized APIs, testing and App Store/Play Store-ready builds I can share relevant live work and discuss the architecture, milestones and realistic delivery timeline. Looking forward for connecting.

@ravichedwal

With over 8 years in full-stack development, I bring to the table a deep understanding of Payment Gateway integration. My knowledge spans across not only standard card integrations but also UPI/Wallet providers, which are crucial for the Indian market. Since I value clear communication and clean architecture, you can trust that payments on your ecommerce platform will be flawlessly smooth. In addition to being well-versed in Payment Gateway integration, I have extensive experience in developing highly scalable and secure web and mobile applications; key components needed for your full-scale ecommerce app development project. Efficiency and scalability are qualities that resonate deeply with me and ones I've consistently delivered on during my 145+ successful projects.

For an India-focused commerce platform with cards, UPI/wallets, wish-lists, reviews, and a large catalogue, I’d build the first release around a scalable marketplace core rather than trying to reproduce every Amazon-level feature on day one. I’d recommend React Native for iOS/Android, with Node.js/NestJS, PostgreSQL, Redis, object storage, and a search layer such as OpenSearch as catalogue size grows. My two priorities would be scalability and user experience: fast product discovery, resilient checkout, secure payments, and modular services so future features like sellers, offers, logistics, and recommendations can be added without rebuilding the app. Security would include token-based auth, social login, role controls, rate limiting, encrypted secrets, verified payment webhooks, audit logs, and protected media uploads. For India, I’d integrate a gateway such as Razorpay/Cashfree that supports cards, UPI, and wallets. A relevant example is Mohollla, where I worked on customer, shop-owner, and driver apps for a local commerce platform, with apps live on both Play Store and App Store. Estimated first-release timeline: 16-20 weeks including development, QA, store preparation, and deployment.

@TechizeBuilder

Dear Client, I read "Full-Scale Ecommerce App Development" carefully and understand you need a high-quality eCommerce mobile application that delivers a seamless shopping experience and drives sales. My hands-on experience with Mobile App Development, iPhone, Android, Payment Gateway Integration, Backend Development, API Development aligns directly with what you need. I've built eCommerce applications with product catalogs, category management, advanced search, shopping cart, secure payment gateways, order tracking, user authentication, push notifications, wishlist, coupons, reviews, and admin dashboards — all designed for scalability, performance, and an excellent user experience. A few quick questions to get us started: 1. Do you already have UI/UX designs, or should I design the application as well? 2. Which payment gateway(s) and shipping providers would you like to integrate? 3. Do you need a customer app only, or also an admin panel and delivery partner application? Thanks & Regards, Deepak

@tyronet2

You need a commerce platform that launches with dependable accounts, Indian payments, catalogue browsing, wish-lists, and moderated reviews while retaining a clear path toward marketplace-scale traffic. My profile is new, but I bring 9+ years of experience across Flutter/React Native, e-commerce backends, payment automation, PostgreSQL, APIs, and AWS. I recommend Flutter for consistent iOS and Android delivery, with NestJS or Django, PostgreSQL, Redis, object storage, and queue workers behind a versioned API. The first release should be a focused production MVP; matching Amazon or Flipkart operationally requires later phases for sellers, fulfilment, returns, recommendations, fraud controls, and logistics. Authentication would support OTP/social login, secure token rotation, device/session management, and role-based administration. Razorpay can cover Indian cards, UPI, and supported wallets, with webhook verification and idempotent order handling. Reviews would support verified purchases, images, reporting, moderation, and audit history. At Poundit, I worked on e-commerce systems, checkout flows, payment automation, and scalable database-backed interfaces. I can provide relevant portfolio material without claiming marketplace scale I have not delivered. Is this initially a single-vendor store or a multi-seller marketplace, and what catalogue size and launch traffic do you expect?

@aprkdream

Hi, Your brief points to I am planning to launch an end-to-end ecommerce solution that can stand shoulder-to-shoulder with Amazon, Flipkart, Meesho, Snapdeal and Myntra. The main priority here is getting the workflow working cleanly in production, especially around frontend or dashboard behavior, API or third-party integration, payment or transaction workflow. I can handle the backend, integration logic, and release path using Payment Gateway Integration. I bring 11 years of full-stack development and solution architecture experience. Relevant work includes the Multi-Vendor eCommerce Platform, including catalog, order, vendor, and payment workflows, where stable APIs, business rules, data consistency, and operational visibility were core parts of the delivery. I would cover this through: - Product catalog, categories, inventory-aware product data, and admin workflows - Cart, checkout, order lifecycle, and customer account functionality - Secure payment gateway integration and webhook-based payment confirmation - Vendor, customer, order, and fulfillment APIs with clear validation rules - Authentication, role-based access, and secure handling of customer data - Testing of checkout, payment, order-status, and recovery edge cases before release I would start by mapping the existing flow, edge cases, and integration constraints so the first build already reflects the real business process. If there is an existing codebase, API documentation, or reproducible issue path, I can align the implementation to that from day one. Best Regards, Anil Prajapati
