Freelenchar will be a full-featured mobile marketplace delivered on both iOS and Android. The entire focus is an e-commerce experience, so the build has to feel lightning-fast from product discovery right through to checkout. The checkout flow is critical: I need a secure payment gateway that connects directly with our partner bank so customers can pay without being bounced to a browser window. PCI-compliant handling of card data, tokenisation, and clear error messaging must all be in place before launch. Beyond payments, a smooth sign-up, login and profile area, plus an easily searchable product catalogue, would make the app far more compelling, so please keep flexibility for those modules in the architecture even if we phase them in later. Core deliverable • A production-ready, tested mobile app package (Android & iOS) that processes live transactions through the specified bank gateway and passes store review. Acceptance criteria • Users can add items to cart and complete payment in under three minutes on a mid-range device. • All payment data is transmitted over HTTPS and never stored on the device. • The app ships with clear build/run instructions and a short video walkthrough of the payment flow. React Native, Flutter or Kotlin/Swift are all fine as long as the final build is smooth and maintainable; choose whichever lets you hit the above criteria fastest.

Hello, As the founder of A4Logic with over a decade of experience, I can confidently steer your e-commerce project towards success. I specialize in turning ideas into scalable, secure, and user-friendly products, and your marketplace app fits perfectly within this realm. Specifically, my expertise in mobile app development using languages like Kotlin will ensure a smooth transactional experience for your customers. Combining this with my proficiency in Android and PHP, we can build an app that handles payments securely through your partner bank, providing a PCI-compliant environment where card data is never stored on the device. In addition to these core skills, I am also highly proficient in web scraping, automation, and third-party integrations which may come in handy for your app's catalogue searchability and user profiling. Moreover, with my familiarity in cloud deployment, we can confidently navigate shipping the app after it passes not only the store review but also meets your requirements - users completing payments within three minutes or less using any mid-range device. Let's build something great together! Thanks!

Hello, I read your requirements carefully and understand that Freelenchar requires a production-ready iOS and Android e-commerce app with a fast shopping experience and, most importantly, a secure direct bank payment integration. I have 10+ years of experience in mobile and full-stack development and can build this using React Native or Flutter, depending on the bank gateway requirements. I can implement the product catalogue, search, cart, authentication/profile structure, secure HTTPS communication, tokenized payments, clear payment errors, and production-ready builds for both platforms. I will ensure sensitive card data is not stored on the device, follow the gateway's PCI/security requirements, thoroughly test the complete checkout flow, and prepare the application for App Store and Google Play review. I will work with Agile methodology, provide 2 YEARS OF FREE ONGOING SUPPORT, complete SOURCE CODE, and assist from ZERO TO PUBLISHING. I can review the partner bank's API/SDK documentation and confirm the best technical approach before development begins. I eagerly await your positive response. Thanks.

Hey there, The bank payment flow is the part I would lock down early, especially since the requirement is an in app checkout with no browser handoff, HTTPS only transmission and no card data stored on the device. That integration needs to be proven before the rest of the marketplace is polished. I would keep the catalogue, cart, authentication and profile areas modular so they can expand without making the checkout harder to maintain. For the cross platform build, I would choose React Native or Flutter based on the bank gateway’s SDK/API support rather than choosing a framework first. Do you already have the partner bank’s mobile SDK/API documentation and sandbox credentials available? Best regards, Hammad Hassan

Hi there, Checkout speed and payment security are where this project lives or dies, and that's directly in my wheelhouse — I've integrated a bank's own gateway API with in-app card entry and tokenization before (not just hosted Stripe/PayPal checkout), so no browser bounce, PCI- compliant handling, and card data that never touches the device. How I'd approach it: - Native in-app checkout wired to your partner bank's gateway — tokenized card data, HTTPS throughout, no local storage - Clear, actionable error messaging on failed/declined transactions - Flutter for cross-platform delivery (Android + iOS) with a performance budget targeting sub-3-minute cart-to-payment on mid-range devices - Architecture kept modular so sign-up/login/profile and product catalogue slot in cleanly when you're ready to phase them in Deliverables: 1. Production-ready, tested app on both platforms, live transactions through your bank gateway 2. Build/run documentation 3. Short video walkthrough of the full payment flow Happy to start with the payment module as the first milestone since it's the highest-risk piece — get that proven, then layer in the rest. Best, Chirag

Hi, I can show you my similar E-Commerce platform and i understand the biggest pain points are the bank gateway integration, PCI/tokenisation requirements, and keeping checkout fast without redirecting users externally.

The architecture will support secure authentication, product search, cart, checkout, and future profile modules while keeping payment data out of the device. i will handle HTTPS communication, tokenised payments, error handling, real-device testing, store submission, build documentation, and the requested payment-flow walkthrough. Question which partner bank and payment gateway/SDK will be used, and do they already provide a mobile SDK for in-app card payments?

The biggest risk here is getting the marketplace experience right while treating the bank payment gateway as a first class part of the architecture, not an integration added at the end. I can build the iOS and Android app with a fast product to cart to checkout flow, while keeping card data out of the device and application database. I’d recommend Flutter for a single maintainable codebase, with a modular architecture for authentication, profiles, catalogue, cart and checkout. I’ll integrate the partner bank gateway using its supported tokenisation/API flow, enforce HTTPS, handle payment states and failures clearly, and test the complete transaction flow on real mid range devices before submission. Estimated timeline: 5 to 7 weeks, including UI implementation, catalogue/cart, payment integration, testing, store compliance, documentation, and the payment walkthrough. VALUE SUGGESTION: I’d isolate the payment gateway behind a dedicated payment service rather than coupling it directly to checkout. This keeps the app flexible if the bank changes its API or you later add another payment method. Which partner bank and payment gateway/API documentation will be used, and does the gateway provide native mobile SDKs or require API based tokenisation?
