React Native (Expo) Mobile App Developer for Startup Fundraising Platform

@Srashtasoft

Hi, I carefully reviewed your requirements. This is a comprehensive Startup-Investor platform involving authentication, fundraising, investor discovery, proposal management, real-time chat, subscriptions, payments, notifications, and Firebase integrations. I have experience with React Native, Expo, Firebase, REST API integrations, JWT authentication, payment gateways, and real-time applications. The existing backend APIs significantly reduce development time and allow focus on building a stable, scalable mobile experience. However, I want to be transparent: the scope you've outlined is closer to a full-scale startup platform than a basic mobile app. Features like Firebase chat, proposal workflows, subscription billing, KYC verification, investor matching, push notifications, analytics, Android + iOS deployment, testing, documentation, and post-launch support represent a substantial amount of work. I can provide regular GitHub commits, test builds, API integration, Firebase setup, deployment assistance, and ongoing support. Happy to discuss the most practical roadmap for delivering a production-ready application. Best Regards, Jemin Sagar

As the lead developer at Carol Data Technology, I am highly experienced in creating mobile applications with a strong focus on React Native – Github being my core knowledge base. Over the past 10 years, I have delivered several high-quality mobile applications, which is exactly what you're looking for your Startup Fundraising Mobile Application. Additionally, I am well-versed in using the Expo framework as well as integrating APIs - making me an ideal fit for this project. You’ve already developed your backend APIs and now need them seamlessly integrated into your application. Stumble-free API integration is one of the key areas where I excel. Moreover, I have hands-on experience working with Firebase Realtime Database / Firestore and Firebase Cloud Messaging (FCM) - perfect fits for the real-time features and chat system that you require excessively. A smooth user experience should be a priority for any application and to optimize that, I'll deploy the JWT authentication system and secure session management. Furthermore, my profound knowledge of Laravel would come handy in integrating JSON-based APIs. My familiarity with creating dynamic UIs with React Native will also ensure responsive tablet support – complementing your requirement list perfectly!

Hello, I have 10+ years of experience in mobile and full-stack development with strong expertise in React Native (Expo), Firebase, and real-time application systems. I have built production-grade mobile apps involving authentication systems, chat modules, API integrations, subscription models, and payment gateways. Your startup fundraising platform is well-defined, and I can develop the complete React Native Expo application by integrating your existing REST APIs and Firebase services to deliver a scalable, production-ready mobile solution for both iOS and Android. I ensure clean, maintainable code with proper documentation and regular updates during development. I am comfortable working within your 60-day timeline and structured GitHub workflow. I can share relevant React Native, Firebase, and marketplace-style app experience during discussion along with live references. Best regards

Your Firebase real-time chat will fail if 50 investors message the same startup simultaneously without implementing message throttling and offline queue handling. I've seen this crash production apps during demo days when investor interest spikes. Before architecting the solution, I need clarity on two things - What's your expected concurrent user load during peak fundraising events? And does your existing API support webhook callbacks for proposal status changes, or will we need to implement polling? Here's the architectural approach: - EXPO + REACT NATIVE: Build modular screens with React Navigation deep linking so investors can jump directly to startup profiles from push notifications without app crashes. - FIREBASE FIRESTORE: Structure chat collections with composite indexes and implement pagination to handle 10K+ messages per conversation without memory leaks on older Android devices. - JWT + SECURE STORAGE: Store tokens in Expo SecureStore with automatic refresh logic to prevent session expiration during active fundraising calls. - RAZORPAY + STRIPE: Implement idempotent payment flows with retry logic and webhook verification to prevent duplicate subscription charges during network failures. - PUSH NOTIFICATIONS (FCM): Set up topic-based messaging so you're not hitting Firebase quota limits when broadcasting to 1000+ startups about new investors. - OFFLINE-FIRST ARCHITECTURE: Cache proposal drafts and investor profiles locally using AsyncStorage so startups don't lose work when switching between WiFi and mobile data. I've built 8 fundraising and investor matching platforms including one that scaled to 12K startups and 3K active investors. The verification bottleneck you described will require a queue system - unverified startups browsing investors creates false engagement metrics. Let's schedule a 20-minute technical call to walk through your API documentation and discuss edge cases like handling proposal rejections and subscription downgrades before I commit to your timeline.
