Hi — Elias here from Miami. I see you're looking to enhance your React Native app, which is currently at an MVP stage. The goal here is to elevate functionality and user experience for a successful launch. A common issue in projects like this is balancing the need for new features with maintaining stability. You'll want to ensure that the app is not only scalable but also easy to maintain as user demands evolve. The tricky part is usually integrating payment gateways and ensuring a seamless experience across both Android and iOS platforms. My approach would involve breaking down the app's current architecture to identify areas for improvement. I focus on building a robust backend to support future scaling while keeping the codebase clean for easier updates. I’ve worked on similar upgrades, ensuring that enhancements are user-centric and technically sound. A few questions to better understand the scope: Q1 – What specific features do you envision implementing to move beyond the MVP? Q2 – How do you foresee handling user roles and permissions, especially concerning payment processing? Q3 – Are there existing integrations that need to be maintained or improved during this upgrade? Happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.

HELLO, I CAN TAKE YOUR EXISTING REACT NATIVE APP FROM MVP LEVEL TO A STABLE, POLISHED AND IOS-READY PRODUCT. I have carefully reviewed your requirements and understand that the priority is strengthening the existing app first: reliable payment integration, fixing navigation and crashes, improving the UI/UX and performance, then completing the iOS release. I have 11+ years of software development experience and can work with your existing React Native codebase, integrating Stripe, PayPal and a suitable payment gateway for Liberia/West Africa while keeping the implementation aligned with Google Play and App Store requirements. I’ll focus heavily on fixing broken navigation, resolving crashes and data-display issues, improving performance, refreshing the interface and making sure the overall experience is consistent across Android and iOS. The project will include sandbox and live payment flows, documented before/after performance improvements, a stable production build, iOS certificates and provisioning, TestFlight testing, App Store Connect submission and release support. I can work iteratively with your existing codebase, first stabilizing the current application and then moving through payments, UI polish, performance optimization and the final iOS launch. I CAN SHARE RELEVANT REACT NATIVE, PAYMENT INTEGRATION, PERFORMANCE OPTIMIZATION AND IOS APP STORE PUBLISHING WORK AND DISCUSS THE BEST TECHNICAL APPROACH FOR YOUR APP. Thanks, Christina

@starttechno

I’d begin by tracing the sections that leave users stranded, then route PayPal, Stripe, and a Liberia-ready gateway through the existing user accounts—not separate payment identities. I’ll stabilize navigation and data states first, refresh the UI, tune slow paths, and validate sandbox/live flows against Google Play and App Store payment rules. Within 7 days, I’ll deliver the updated React Native source, before/after performance notes, maintenance hand-off, and a signed iOS build in App Store Connect with provisioning, certificates, and TestFlight configured; I’ll support any Apple review fixes. SwiftKhata, my cross-platform POS app, was approved for iOS and the Mac App Store, including the signing/release workflow. Is the Liberia gateway already chosen, or should I validate Orange Money versus MTN Mobile Money first? Muhammad Saad

@Hubready

Hello!, I am a US-based senior software engineer and I’d love to help take your React Native app from MVP to a polished, launch-ready product. The real challenge here is usually not just adding features, but tightening stability, UX, and release readiness so the app feels solid on both iOS and Android. I can help by: 1. Reviewing the current app and spotting the biggest product and technical gaps 2. Prioritizing the highest-impact upgrades first 3. Improving payment flow, fixing bugs, and polishing the UI/UX 4. Testing everything carefully so the launch is smooth I pay close attention to the details that often get missed, especially when an app is already live and needs to move beyond MVP without breaking what works. If you want someone who will treat this like a real product and not just a quick code task, I’m a strong fit. A few relevant examples of work I’ve handled: - A React Native wellness app with subscription billing - A logistics app with live status syncing and offline support - A small ecommerce mobile app with secure checkout flow Could you please clarify the following questions to help me better understand the project? 1. What are the top priorities: UI polish, payment integration, bug fixes, or new features? 2. Is the iOS version already in progress, or does it need to be built and submitted from scratch? 3.

@adeelpirzada

Broken navigation is the right thing to fix first, since routing bugs will corrupt any UI refresh and payment flow you layer on top. I'd start by auditing the React Navigation stack and state handling, clear the dead routes and related crashes, then wire Stripe and PayPal through your existing account model with server-side verification so sandbox and live keys are cleanly separated. For West Africa, Flutterwave usually gives the widest mobile money and card coverage in Liberia. iOS comes last: certificates, provisioning, TestFlight round, then submission with the payment rules reviewed against App Store guidelines beforehand. I've shipped React Native apps with Stripe billing and handled the full App Store release cycle. Do payments settle to your own backend today, or is there no server-side layer yet?

@bcosley

Hi, You're upgrading a React Native app that’s live but MVP-level, aiming to mature payments, polish, and a clean iOS launch. I’ve delivered RN upgrades with PayPal and Stripe before, plus a regional gateway through sandbox and live environments, while preserving the existing user account flow and Play/Store constraints. I’d start by validating the current navigation flow and payment wiring, then enable PayPal, Stripe, and a West Africa gateway, fix broken links, and push a polished UI that aligns with guidelines. One technical risk: payment gateway wiring can drift between sandbox and live, causing mismatches in receipts or auth flows. What West Africa gateway should we add beyond PayPal and Stripe, and do you have sandbox credentials for it? What is your target rollout plan for TestFlight and Play Console updates, and which performance metrics will you treat as success? If we're aligned, I'd be happy to walk you through the implementation plan before we get started. Best regards, Brandon

@msaqibimran

Hi, I see the need for a more mature version of your app before launching on iOS. I estimate we can deliver a polished update, including payment integrations and a refined user experience, in about 30 days. To align on scope, could you specify which West African payment gateway you’re considering? Also, are there particular UI/UX improvements you have in mind beyond fixing navigation issues? For the approach, I’d start by implementing the payment systems in both sandbox and live modes, ensuring they integrate seamlessly with user accounts. Fixing navigation will come next, focusing on a smoother interface that adheres to platform guidelines. I also have expertise in mobile app development, particularly with React Native, which will be beneficial for the iOS submission process. The tentative price for this project is $4000, and we can adjust that as the scope is finalized. Looking forward to discussing the details further. Best regards, Mohammad

Your app’s stuck navigation and payment setup need focused fixes to get it ready for iOS smoothly. I’ve helped clients with similar live React Native apps, upgrading payment flows and cleaning up navigation bugs that caused crashes and user frustration. For payments, do you prefer integrating the West African gateway via their official SDK or a custom API wrapper? Also, handling Google Play and App Store payment policies side-by-side can be tricky—should we consider a shared payment module or separate logic per platform? I’ll start by fixing the broken links and navigation routes to eliminate dead ends, then enhance UI polish for a fresher, smooth experience. After stabilizing the code, I’ll integrate PayPal, Stripe, and the West African gateway in sandbox and live modes while linking everything to your existing user accounts, respecting platform rules. Once stable, I’ll handle the iOS certificates, provisioning, and submission workflow including TestFlight testing. You’ll get performance metrics before and after, plus a clear hand-off guide so your team can maintain it easily. Ready to discuss the technical approach and milestones to get this upgraded and launched on iOS with confidence.

Your goal of elevating your React Native app from MVP to a polished, market-ready product for iOS launch, especially with robust payment integration, aligns perfectly with my experience in enhancing existing mobile applications. I've successfully implemented similar multi-payment gateway solutions for e-commerce platforms, ensuring seamless user experiences and strict adherence to platform guidelines. My approach will involve a phased integration of PayPal and Stripe, leveraging their respective SDKs within your existing React Native architecture. For localized payment providers, I propose building a modular payment service layer that abstracts provider-specific logic, allowing for easy addition of new gateways with minimal refactoring. This will be coupled with a UI/UX audit and targeted performance optimizations using React Native profiling tools to address your quality and polish requirements. To ensure the best outcome, could you clarify the expected transaction volume and any specific regional payment preferences beyond PayPal and Stripe? I'm eager to discuss how we can achieve a smooth and successful iOS launch.

@extreamcode

Hi there, I can see the real challenge isn’t just upgrading a React Native app , it’s turning a live MVP into a stable, App Store-ready product with payments that behave correctly across regions and policies. I’ve handled React Native fixes, Stripe/PayPal integrations, routing issues, performance tuning, and iOS release workflows, so I can tighten the app, clean up the broken navigation, and guide the build through certificates, provisioning, TestFlight, and App Store Connect. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. I’ll also review the best West Africa-friendly gateway option based on your target countries and account flow, so the payment stack fits both your business model and store guidelines. Which West African markets must the gateway support first, and do you already have merchant accounts or preferred providers in mind? If you’d like, I can start by auditing the current codebase and mapping the payment + release milestones first. Looking forward to your reply so we can finalize the exact plan. Best regards, Asad
