Tell about your failure in IT experience.

In one of my projects, I faced a problem with improper state management in a React application. Due to the lack of a clear state architecture and excessive use of local component state, the application started behaving unpredictably: data was not synchronized between components, and bugs occurred during UI updates.

I realized that I needed to use centralized state management, such as Redux or Context API, and I reworked the logic. This experience taught me the importance of planning the application's architecture and using appropriate tools for state management, especially in large projects.
