A production-grade, privacy-first mobile application built for cross-platform insurance policy lifecycle management. Developed across five iterative milestones to solve real family financial tracking challenges, featuring automated policy document OCR, intelligent clause extraction, and interactive schedule analytics.

Engineered with a zero-leakage security posture: replaced insecure legacy XOR scaffolds with authenticated AES-256-GCM encryption for stored records. Designed an on-device Retrieval-Augmented Generation (RAG) pipeline allowing natural language querying over confidential policy clauses without sensitive financial data ever leaving the user's phone.
