Technical Case Study
The Challenge
Building a digital tool for 12-step recovery presents a unique conflict: users need powerful, AI-assisted insights, but the nature of the work (inventories, resentments) requires absolute privacy. Storing this data on a central server creates a liability.
The Architecture
I architected a "Local-First" solution using React Native. This ensures the app feels native on both iOS and Android while adhering to strict data sovereignty principles.
- Core Tech: Built with React Native (Expo) for a unified codebase deployable to both Apple and Google ecosystems.
- Data Privacy: iOS data is stored 100% locally (SQLite). Android uses Firestore with strict security rules—datasets are siloed by anonymous user IDs, making them inaccessible to admins.
- On-Device AI: Privacy-preserving AI logic runs locally to analyze tone and provide feedback without sending personal journal entries to the cloud.
- UX Design: A minimal, distraction-free interface designed to lower cognitive load during high-stress emotional work.
