Hi there, I can develop a modern React website along with cross-platform React Native apps for iOS and Android that integrate seamlessly with your existing Spring Boot backend while maintaining complete feature parity. I’ll connect the apps to your REST APIs, implement the existing JWT and OTP authentication flows, follow your high-fidelity mockups precisely, and deliver production-ready source code with documentation for deployment and future maintenance. Have your REST APIs already been documented (Swagger/OpenAPI), or will you be providing API documentation separately along with the staging environment? Kindly send me a message to discuss more. Thanks.

Hello, I'd love to help with your "React Native Mobile App & Website Front-end" project. I build fast, pixel-perfect static sites and landing pages in clean HTML5/CSS3 with Bootstrap or Tailwind — fully responsive across mobile, tablet, and desktop. For a fixed project involving java, javascript, mobile app development, android, html5, frontend development, react native, api development, I convert Figma/PSD/XD designs into crisp, semantic markup that matches the design exactly. I deliver lightweight, cross-browser-tested code with smooth load times. I'd be glad to discuss the details and timeline — when can we connect? Final timeline and cost will be confirmed in chat after a complete understanding and documentation of the project expectations in detail.

Hello, I see you're looking to expand your current React web application into a fully integrated ecosystem with a companion website and mobile apps for both iOS and Android using React Native. Leveraging React Native's capability to share code across platforms, I can seamlessly extend your functionalities to mobile, ensuring the front-end aligns perfectly with your existing Java (Spring) API. With extensive experience in API integration and front-end development, I'll ensure that the mobile apps and the additional website front-end maintain consistent performance and user experience across all devices. This involves crafting responsive layouts, optimizing load times, and implementing features using React Native’s robust libraries and tools. Let's create a cohesive experience across all platforms, connecting your users continuously to your services through intuitive and high-performing interfaces.

Hi, I’m a senior developer with 20+ years of experience, Top Rated on Freelancer.com with 1,500+ completed projects and a 5-star record, and I’ve built React Native apps and web front-ends tied to Java backends before. I’ll start by reviewing your mockups and API docs, then set up the React Native project with the exact same UI surface as your mockups while keeping the existing authentication flows (JWT + OTP) intact. The mobile codebase will share API calls with the new React website front-end, so both clients stay in sync with the same backend logic. I’ll handle secure token storage on device, validate OTPs locally before server confirmation, and ensure the apps compile cleanly for App Store and Play Store submission with zero regressions in your staging environment. I’ll provide a README with build, run and release steps so your team can take it from there.

@Hammadhassan21

Hey, I’ve carefully reviewed your project, and I understand you need to extend your existing React and Java Spring application into a complete cross-platform experience with a matching website frontend and React Native mobile apps. I can help you deliver feature parity while keeping the existing backend logic stable and reliable. I will build the React frontend, develop iOS and Android apps in React Native, integrate your existing REST APIs, and implement the JWT and OTP authentication flows using your current backend services. I will ensure the apps are responsive, maintainable, properly tested, and ready for store submission with clear handover documentation. I have hands-on experience with React, React Native, API integrations, and authentication-based applications and would be happy to review your mockups and API documentation. One quick question: Is your existing React web application using any specific UI framework or component library that should be maintained?

@elishadiah326

Hi, Thank you for posting the great project! Your project is a great match for my experience with React, React Native, REST APIs, and modern authentication flows. I enjoy building clean, responsive applications that deliver a consistent user experience while keeping the existing backend and business logic untouched. I understand that feature parity is essential. I'll develop the React website and React Native apps based on your high-fidelity mockups, integrate seamlessly with your Java Spring REST APIs, and implement the existing JWT and OTP authentication flows without changing the backend. The final deliverables will include clean, maintainable source code, Git repository updates, and concise hand-off documentation for build, deployment, and release. I have a couple of questions: - Could you share the mockups and API documentation for review? - Is the current React web application available as a reference, or will the new website be built independently with the new design? Looking forward to working with you for the long term. Best regards, Diah

@ska234

Hi. To build this cleanly, I’ll keep your Spring API as the single source of truth and wire the React web front end plus React Native iOS/Android apps to the same REST, JWT, and OTP flows. I’ll translate your mockups into modular screens, shared service layers, and a maintainable auth/navigation structure so the mobile experience feels native while staying fully aligned with existing business logic. I’ll also package the apps for App Store and Play Store release readiness and include hand-off notes for build, run, and deployment. As a Senior Full-Stack Developer, I have mastered React, React Native, JWT authentication, OTP integration, REST APIs, and Spring-backed app delivery, and have strong experience in web-to-mobile parity projects. I am sure I can deliver high-quality results within the right timeline based on project size. Let’s get in touch and discuss more. Thanks.

@denisSolution

Hi, I can translate your React web app into a React Native mobile experience while keeping the existing Java backend intact, focusing on clean JWT/OTP auth flows and visual parity with your mockups. I recently built a React Native companion app for a Java backend where we reused the same REST endpoints and auth flows, though we had to adjust the state management for offline use. I'd approach this using modular React Native components with shared API utilities because it keeps the codebase consistent while allowing mobile-specific UI optimizations. The biggest improvement will come from strict TypeScript typing between frontend and API layers. I'll keep the authentication flows tightly coupled to your existing endpoints and provide clear documentation for App Store submissions. This ensures your users get a familiar experience on mobile without duplicating backend logic. If we're aligned, I can start right now. Thanks, Denis
