I’m building a mobile app focused squarely on personal financial management, and the first milestone is a rock-solid expense-tracking module. The core goal is to let users record, categorize, and review their day-to-day spending from any iOS or Android device. Here’s what I need right now: • Intuitive screens for adding expenses on the go—receipt upload, amount, category, date, notes. • A clean dashboard that summarizes spending by category and shows simple charts. • Secure local storage plus cloud sync so data is never lost. • Lightweight user authentication (email or social sign-in). • Codebase in React Native or Flutter—whichever you’re most comfortable shipping to both stores quickly. While the priority is expense tracking, I’d like the architecture left open for future budgeting tools and investment management features, so please keep modularity in mind. Deliverables include: 1. Clickable prototype (Figma or similar) for approval. 2. Full source code with clear comments and README. 3. Basic test suite covering key flows. 4. A concise hand-off document explaining build, deploy, and how to extend modules. If you’ve shipped financial apps before or have strong payment/fintech security experience, that’s a big plus. Let me know which framework you prefer, relevant portfolio links, and your estimated timeline for MVP completion.
