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.
