Challenges:

The application required several interconnected workflows including service discovery, appointment booking, real-time communication, notifications, payments, and user-specific application states. The challenge was maintaining predictable navigation and state behavior while supporting these workflows across iOS and Android.

Solution:

Contributed to the React Native and Expo application using Redux Toolkit for predictable state management and React Navigation for structured navigation flows. Socket.io was used for real-time communication, while reusable booking and marketplace components helped maintain consistency across features. Push notification infrastructure was integrated to keep users informed about relevant application events and workflows.
