I need an experienced React Native developer (or a small, tightly-knit team) to turn a fully documented product spec into a cross-platform personal finance and habit-building app for iOS and Android. All wireframes, user flows, and the complete design system are ready; you’ll receive them after we sign an NDA. Key build requirements • Implement user authentication with Email and password during onboarding. • Create smooth onboarding screens that introduce the finance-plus-habit concept. • Build a transaction logging module that lets users enter, edit, and categorize expenses or income. • Display spending summaries on a Home dashboard using Lists and tables, keeping the look crisp and lightweight. • Add a daily interaction system: scheduled push notifications, streak tracking, and small rewards that encourage users to log both finances and habits. • Integrate Supabase for the backend: real-time data sync, secure storage, and serverless functions where needed. • Ensure clean UI execution, pixel-perfect alignment with the provided design system, and subtle animations that feel native on both platforms. Scope and expectations • Codebase must be TypeScript-ready, well commented, and organized for future feature drops. • Deliver an end-to-end solution within roughly six weeks (mes y medio), including one feedback iteration after internal QA. • Before final hand-off, supply build instructions, environment variables setup, and a short Loom or similar walkthrough of the code structure. If you’ve shipped finance, wellness, or productivity apps with React Native and Supabase, and you know how to balance performance with delightful micro-interactions, let’s talk.

Hi, This is Elias from Miami. I checked your project description and understand you’re looking to develop a finance app using React Native that meets user needs efficiently. It sounds like an exciting opportunity to combine finance with mobile technology! I’ve worked on several similar finance applications and understand the key technical challenges involved. I believe a user-friendly interface and robust performance are crucial for this type of app. I’d be happy to go through the details and suggest the best technical approach. My plan would include discussing the UI/UX design to ensure it’s intuitive, setting up secure backend integration, and implementing rigorous testing for reliability. I have a few questions to get a better understanding: Q1 – What specific features do you envision for user authentication in the app? Q2 – Are there any existing systems or APIs you’d like to integrate with? Q3 – How do you plan to handle data security and user privacy in the app? Looking forward to hearing from you.

Interesting project, I will deliver the full React Native app — onboarding flow, transaction logging module, home dashboard with spending summaries, and the daily interaction system with streak tracking and push notifications — all wired to Supabase for auth, real-time sync, and serverless functions. One thing I will architect early: an offline-first transaction queue using MMKV for local storage so users never lose a log entry on a flaky connection. Entries sync to Supabase the moment connectivity returns, and the streak counter stays accurate because it validates against local timestamps — not server round-trips. This keeps the habit loop tight even underground or on airplane mode. Questions: 1) For push notifications, are you targeting Expo's notification service or a direct integration with FCM/APNs? Looking forward to talking through the details. Kamran

Your plan to combine finance and habit tracking in one app is smart, and this can be nailed by focusing on smooth onboarding and a lightweight dashboard. For user authentication with email and password, I suggest starting with Supabase’s auth and customizing onboarding flows for clear, calm guidance—this helps build user trust early. The transaction logging module can use flat lists with editable rows so users quickly add or change entries without hassle. For the daily interaction system, I recommend using local notifications tied to server data so reminders stay in sync, and a simple streak counter that updates live. I’ve built a wellness app with a scheduling and rewards system that pushed engagement by 30%, plus a finance tool with intuitive expense categories and real-time backend updates via Supabase. Matching your pixel-perfect designs with subtle animations is doable—I usually break animations into reusable components for consistency across iOS and Android. A couple of questions: Do you want transaction categorization to support custom categories later? Should push notifications work offline or only online? I can deliver a clean, well-documented TypeScript codebase in six weeks with one iteration after your team’s review. Ready to dive in once the NDA is signed.

Having recently delivered a secure fintech dashboard using React Native, I understand the precision required to translate detailed documentation into a high-performance mobile interface. I have a strong track record of turning complex specifications into production-ready code while maintaining the exact visual fidelity requested. My approach prioritizes a clean, scalable architecture that ensures financial data remains secure and the user experience remains fluid across both iOS and Android platforms. I will build the application using a TypeScript-first approach to ensure type safety across your financial data models and transaction states. For state management, I recommend Redux Toolkit or Zustand to handle real-time updates efficiently, paired with React Native Reanimated for high-performance UI transitions. I will implement secure storage for sensitive credentials and use Axios with robust interceptors for encrypted API communication, ensuring the app meets industry standards for both security and speed. Regarding the backend, do you already have the API endpoints fully documented, or will we need to coordinate on the integration of specific third-party KYC or payment providers? I’d also love to know if you have a preferred CI/CD setup for automated deployments to the App Store and Google Play. I am available for a quick chat or call to align on your technical roadmap and can start as soon as you are ready—let me know when is best for you to discuss the next steps.

Hello, I will build the app in React Native + TypeScript on Supabase: email/password auth and onboarding, transaction logging (enter/edit/categorize), Home dashboard summaries, push notifications via FCM/APNs through Supabase edge functions, server-side streak tracking, and animations via Reanimated 3 so motion runs on the UI thread. Two flags worth raising. Streak tracking belongs server-side, not on device: client-clock tampering or timezone shifts break local counts; calculate against UTC plus the user's timezone in a Supabase function. Finance apps also need offline logging; Supabase has no native offline, so a local SQLite layer with a sync queue is the workaround. Questions: 1) Push notifications branded (custom server) or standard via Expo? 2) Local-first/offline support in scope for v1, or online-only? Looking forward to talking through the details. Faizan

Hi, This is a strong fit because this is the kind of product where execution quality matters as much as functionality—especially with finance tracking and habit engagement living in the same experience. With React Native + TypeScript + Supabase, this can be built as a clean, scalable cross-platform app with one shared codebase while keeping native-feeling performance. I’d approach it in layers: authentication and onboarding first, then transaction tracking and dashboard logic, followed by the habit/streak engine, notifications, rewards, and final polish around animations and UX details. Supabase is a strong choice here for auth, real-time sync, storage, and edge/serverless logic, and I’d structure the codebase with future feature growth in mind rather than treating this as a one-off MVP. I also like the focus on pixel-accurate execution and micro-interactions—that’s often what separates a finance utility from a product people return to daily. Given the six-week target, I’d likely phase delivery in incremental milestones so core functionality can be validated early while polish continues in parallel. That reduces risk and keeps momentum high.
