what i built

Architected a full-stack cross-platform mobile app in React Native and TypeScript for small-group event coordination, built around a novel co-commitment mechanic to reduce event cancellations.
Designed a PostgreSQL-backed event lifecycle with Supabase database triggers that invoke serverless Deno Edge Functions to deliver real-time push notifications.
Implemented Row-Level Security for group-scoped data visibility, a Quick Add recommendation engine, and an optimistic-update UI layer via TanStack Query for low perceived latency.
