Projects

A shared expense tracker built on Spaces — switch between a private Personal Space and shared Family Spaces.

• Built a cross-platform mobile app with React Native (Expo) and TypeScript, backed by Supabase (PostgreSQL) for auth, data, and storage.
• Modeled finances around intrinsic Spaces — a permanent private Personal Space auto-provisioned at signup plus shareable Family Spaces joined by a rotatable invite code, with admin/member permissions enforced through Postgres Row-Level Security.
• Implemented per-month budgets with auto-carry from the prior month, a DB-enforced category list, and denormalized logger names so a departing member's expenses persist in the shared ledger.

A prediction system for visualizing team performance trends.

• Engineered a prediction system using Python for data processing, Scikit-learn for machine-learning pipelines, and a React front-end to visualize predictions and team performance trends.
• Validated model behavior by comparing predicted vs. actual outcomes and analyzing error distributions throughout training.
