What I Did

Took a legacy Ionic/React app from staging to production. Cleaned the codebase and engineered a complex hierarchical user architecture (children, parents, families, super admins). Implemented mobile payment gateways, BLE smartwatch sync, manufacturer hardware comms, and automated webhooks for Fitbit & Strava.
