I developed customer-facing web apps using Django REST Framework and React Native. One React Native mobileapp experienced frequent crashes due to performance issues. To resolve this, I optimized the app by implementingmemoization to reduce re-renders and used caching and query optimizations for the Django backend. As a result, theapp crash rate decreased by 90%, leading to improved customer retention due to enhanced responsiveness andstability.
