Hi, I understand you already have a MERN-based billing platform and need a lightweight React Native companion app that plugs directly into your existing REST APIs. Since the scope is tight and APIs are ready, this is mostly about clean mobile implementation and state handling. I can build the app with three focused screens: Inventory: real-time stock view, add/remove items, category-based filtering Invoices: create new invoices, edit existing ones, and trigger email dispatch Reports: generate sales and inventory reports and export them as shareable PDFs I’ll keep the UI native to React Native components and use Redux Toolkit or Context where it actually helps, not just for the sake of it. The app will be structured cleanly so it’s easy to maintain and extend later. Since you’re providing API docs, sample payloads, and a Postman collection, I can focus entirely on the mobile side and make sure everything runs smoothly against your staging server. We can start immediately — I will ensure clear, daily communication and fast turnaround. You’ll always know the exact progress. Lets connect over chat so we could discuss the details.

I appreciate the opportunity to introduce myself and my team at Prajapati Technologies for your React Native project. While our primary focus has been on web development, as you've seen in my profile we do have significant experience across multiple platforms including Android and iPhone app development, which are crucial for your project.

@MshafiqDev

With your project's focus on speed, functionality, and mobile optimization, my skills and experience align perfectly. I bring over six years of specialized expertise in WordPress, Shopify development, Speed Optimization, Bug fixing and Figma Design- deep understanding of these platforms allows me to develop high-performing, mobile-responsive applications with ease. Given that React Native is Javascript-based (just like Wordpress and Shopify), my proficiency in the language can be directly channeled to building your ideal billing companion app from scratch. Besides being a developer, I boast mastery at tackling challenges creatively which becomes apparent in areas like bug-fixing and speed optimization. These qualities will help me ensure your app runs smoothly even under heavy use and loads super-fast which I believe are the key characteristics you desire for your app-pagination. Lastly, the solid communication channels I maintain would ensure quick updates and minimal or no errors during collaboration. You would be provided with concise commits and a short loom walkthrough ensuring no surprises are embarked upon at any stage of the project, thus making the journey together smooth despite the challenges we may face

@kishanbwts

I can build the React Native companion app with the three screens you described, integrating directly with your existing REST API. I have experience connecting mobile apps to MERN stack backends and handling real-time inventory updates. Using Redux Toolkit will help keep state predictable and manageable across screens. For the Inventory screen, I’ll implement live stock updates and dynamic filtering by category, ensuring smooth add/remove item workflows. The Invoice screen will support creating, editing, and emailing invoices, leveraging your API endpoints. For Reports, PDF export will be handled with a lightweight library that works well on both platforms. Before starting, could you confirm if any authentication flows or token refresh are needed on the app side? Also, do you prefer any specific libraries for PDF generation or emailing, or should I pick the most stable React Native options? I’ll provide clear build instructions and environment variable details, plus a TestFlight and APK build for you to test. Clean commits and a Loom walkthrough explaining the app structure and usage will be included. Looking forward to your API docs and Postman collection to get going.

@jagratip3

Dear Client, I’d be glad to help you implement a secure and maintainable authentication flow in your existing Flutter application. I have strong hands-on experience with Flutter and Firebase Authentication, including email/password sign-in, role-based access control, and persistent auth state management. I understand that your core screens are already in place, so my focus will be on seamlessly integrating authentication without disrupting your current architecture or UI theme. I’ll ensure the login and registration screens visually match your app while following best practices for security and session handling. For roles, I typically use Firebase Auth + Firestore (or a similar backend) to assign and store user roles at sign-up, enabling clean gated navigation so Admin-only screens remain inaccessible to regular users. The auth state will persist across app restarts, with proper handling for sign-out, email verification, and password recovery. All code will be clean, modular, and well-commented, and I’ll include a short README explaining the auth flow, role logic, and where to extend it later. Key points I’ll cover for your project: Email & password registration and login in Flutter Email verification, password reset, and secure sign-out Persistent auth state management (Firebase Auth) Admin vs User role assignment and route protection I can start immediately and deliver a reliable, production-ready auth flow. Let’s get started. Best regards,

@technoJaipur

Hello there, I am having 9+ years of experience building mobile applications. Having said that I can help you with React Native app that integrate with your existing REST APIs. I will map the three screens (Inventory, Invoice, Reports) directly to your current workflows, focusing on clean UI, real-time updates, and reliable PDF export. Quick Questions: 1 - Do you already have PDF generation endpoints? 2 - Will authentication reuse your existing token/session flow? Let's connect over chat for more clarity on what are you aiming for.

@seventysixeast

We can build your react native app, some of our react native projects fow which even the apis were developed by us, though that is not a requirement in your case. However if need be, we can also that changes in the mern stack api. - edvantum app for schools and parents for activity management and tracking - mysnps66 app for payment of fees by parents - Envolve education app (webapi slimPhp) - CliniCare App for Patients & Practitioners (webApi node, Chat & Video features)

@urrj2004

Hello, I hope you are doing well. I can surely do this and build a clean, lightweight React Native companion app that integrates smoothly with your existing MERN backend. The flow would be to wire the app directly to your REST APIs, build the three screens with real-time data handling, then add PDF export and email triggers exactly as in the web app. I have solid experience building React Native apps that consume existing APIs, handle state cleanly, and ship stable Android and iOS builds. I’m confident I can meet your goals and deliver well-structured code with clear docs and a smooth handover. Two questions: 1) Do you already have authentication handled via token (JWT) for mobile, or should the app include a login flow? 2) Do you prefer any specific library for PDF generation and file sharing, or should I choose the most stable option? Best regards, Rajat J

Hello I have 6+ years of experience in web and mobile development, including 5+ years specializing in React Native, and I’m confident I can deliver a lightweight, production-ready companion app for your existing MERN-based billing platform. Since your REST APIs, documentation, and Postman collection are already available, I can focus entirely on the mobile side and ensure a smooth, stable integration. The app will include three core screens: an Inventory screen for real-time stock management with category-based filtering and search; an Invoice screen to create, edit, and email invoices directly from the device; and a Reports screen to generate sales and inventory reports with instant PDF export and native sharing. I’ll build the app using clean, well-structured React Native code for both iOS and Android, leveraging Redux Toolkit where appropriate for reliable state management, along with proper error handling and performance optimization. Final deliverables will include the complete source code, a clear README with build instructions and environment variables, and release-mode builds (APK and TestFlight) connected to your staging server to ensure everything runs smoothly. Thanks
