Hello, your "Full Stack Developer (Flutter & Node.js)" project is right in my wheelhouse. I build modern JavaScript apps end to end — React/Vue/Next on the front and Node/Express on the back, in TypeScript where it helps. Working with javascript, mobile app development, css, html5, node.js, express js, react.js, full stack development, flutter, api development, I focus on responsive, fast UIs, clean component structure, and reliable APIs — no page-builder shortcuts. I can lock down the scope and key flows first, then ship in reviewable increments. Can we hop on a quick chat to align on your requirements? ⭐ 5.0/5 from a recent client: "Very Professional and On time delivery of the project" Final timeline and cost will be confirmed in chat after a complete understanding and documentation of the project expectations in detail.

Your payment gateway integration will fail at scale if you're not handling webhook retries and idempotency correctly. I've seen production apps lose thousands in revenue because Stripe webhooks got dropped during network hiccups. Quick question - are you processing payments synchronously during checkout, or do you have a queue system to handle failed transactions? Also, what's your current approach for handling Apple Pay domain verification across multiple environments? Here's the architectural approach: - FLUTTER + NATIVE INTEGRATIONS: Build platform channels for Google Pay/Apple Pay that handle tokenization securely and pass PCI compliance audits without storing card data. - NODE.JS + EXPRESS: Design a microservices backend with rate limiting, JWT auth, and Redis caching to handle 5K concurrent users without choking your database. - PAYMENT GATEWAYS: Implement webhook handlers with exponential backoff retry logic and idempotency keys to prevent duplicate charges when Stripe/PayPal webhooks fire multiple times. - TWILIO API: Set up SMS queuing with SQS to handle delivery failures and rate limits when sending OTPs or booking confirmations at scale. - REACT.JS OPTIMIZATION: Use code splitting and lazy loading to reduce initial bundle size by 50%, critical for mobile users on slow networks. I've built 8 production apps with Flutter that are live on both stores, including 2 restaurant booking platforms that process 10K+ transactions monthly. I don't take on projects where payment flows aren't bulletproof - let's schedule a 20-minute call to walk through your transaction flow and edge cases before we start building.

@kishanbwts

I’ve helped a few startups build scalable apps using Flutter and Node.js, including integrating payment gateways like Stripe and communication tools like Twilio. For your project, I’ll focus on smooth cross-platform mobile development paired with a robust backend in Express to keep things fast and reliable. Do you already have preferred payment gateway providers, or should I recommend the best fit based on your user base? Also, how do you plan to handle app store publishing—will you need support with that process? I’m confident I can quickly address API integrations and optimize performance, as I recently resolved similar challenges for an e-commerce client. Ready to jump in and start building your system end-to-end.

@Aaleen110

I understand you need a Full Stack Developer experienced in Flutter and Node.js for your scalable web and mobile applications, specifically mentioning API integrations and payment gateways. My previous work on a similar e-commerce platform resulted in a 20% increase in conversion rates through optimized payment gateway integration and a streamlined Flutter checkout flow. I will deliver a fully functional cross-platform mobile application built with Flutter, alongside a responsive web application developed in React.js. The backend will be constructed using Node.js and Express, exposing RESTful APIs for communication between the frontend applications and third-party services. Deployment will be handled via Docker containers on AWS. Regarding payment gateway integration, will the chosen gateway require a dedicated webhook endpoint for asynchronous payment status updates? Ready to start as soon as you confirm scope.

@alizain721

A common hidden risk in projects like this is not the tech itself but the way payments, messaging, and deployments are stitched together — without a clear API-first architecture you end up with brittle integrations, slow releases, and unpredictable mobile behavior across iOS/Android. My practical approach: design an API-first backend with clear versioning, build one Flutter codebase for both mobile platforms, and a React.js web client that consumes the same REST APIs. Implement payment flows via Stripe (with Google Pay / Apple Pay passthrough) and Twilio for communications, plus thorough e2e and integration tests before any release to stores. Recommended stack: Flutter (mobile), React.js (web), Node.js + Express (API), PostgreSQL (transactions/bookings), Stripe for payments, Twilio for messaging, Docker + GitHub Actions CI/CD, deploy to AWS (ECS/Fargate or Cloud Run) with Sentry/Prometheus for monitoring. For maintenance and flexibility I suggest modular services, feature flags, automated tests, and staged rollouts to minimize user impact and speed iterations. Similar work: PicMe — a photographer marketplace I helped build (cross-platform booking, escrow payments, Stripe, PostgreSQL, Firebase, real-time chat), which maps closely to your payment/booking needs. Quick question: is this a greenfield build or are there existing apps/APIs and store listings we must integrate with? If you’re free, let’s schedule a 20-minute call to align priorities.

@iimtpradeepdash

I'm not based in Sri Lanka, so you'd need to consider fully remote with location flexibility if you want this build. I meet the rest: I build Flutter mobile (iOS+Android) and React.js web off a Node.js/Express/MongoDB backend, most weeks. Published apps to both stores (see eSignatory, CawGo—live on Android and iOS). On integrations: I set up Stripe, PayPal, Google Pay, Apple Pay, and Twilio on multiple platforms—handling webhooks, payouts, and 2FA/SMS. I deploy to AWS or GCP with Docker, independent, no hand-holding needed. The only blocker is location—we work remote-first but not physically located in Sri Lanka. If you can extend outside Sri Lanka, reply. I can show code and working builds on a call. Pradeep
