Timeline: 7 days | Cost:£200 | Proven experience Hello . I’ve solved this exact problem before and can deliver a secure, React Native expense-tracking app with analytics and offline support in 7 days. Based on my past experience, the real challenge is not the UI, but ensuring offline-first storage and secure authentication without slowing performance. This matters because finance apps fail if data is lost or login is unreliable. On a similar project, careful state management and encryption kept both speed and security intact. To move forward, I only need your design files (if any), preferred analytics layout, and any backend details for syncing. This is a straightforward project for me, and I’m confident in delivering a smooth, secure, and user-friendly finance app. Happy to go into more detail in the chat.

Hello, I’ve reviewed your PayTrack scope and will build a secure, offline-first React Native app for individuals and small businesses that combines biometric/PIN auth, encrypted local storage, role-based business access, automated/manual expense capture, recurring detection, category budgets, real-time analytics and exportable reports. Approach: implement Firebase auth + secure local DB (SQLite/Realm with encryption) synced to Firebase when online; REST APIs for integrations; performant charts (Victory/React Native SVG) and background push notifications for reminders; analytics engine for recurring detection and reports. How to start: provide API specs, Firebase project access, desired chart samples and priority platforms; I’ll deliver an MVP in phases: Auth & storage → Expense flows → Analytics & exports → Polish. Which third-party services (banks, payment providers, or accounting tools) do you need integrated first, and do you have API credentials available? Best regards, MAKSYM

Hey — saw your post about building PayTrack, your smart expense and finance management app in React Native. Most finance apps struggle with keeping data in sync across devices while still feeling fast and secure, especially once real user data and bank connections are involved. Quick question before I suggest an approach: Are you planning to integrate with any specific banking/aggregation APIs (like Plaid, Stripe, Truelayer, etc.), or will this start with manual expense tracking only? I’ve worked on React Native fintech-style apps before with secure auth, transaction views, and budgeting dashboards, so I’m familiar with the performance and security tradeoffs you’ll hit. If you can share your current UI designs, user flows, or a short spec, I’ll review it and tell you what’s realistic for the first version of PayTrack.
