My Role

Built during my internship at Shop My Influence. I worked across the React Native member app, the React admin dashboard, and the Node.js, Express, and PostgreSQL backend.

Challenges

The main issue was handling race conditions when multiple people try to book the last spot in a class at the same time. Fixed it using database transactions and optimistic locking.
