challenges & solutions

I'm working on an existing codebase, the challenges included here are some of my refactorings result.

Inefficient data streaming

The app made abundant connections to firestore streaming, which causes a performance problem and increased bill in Firebase.

Solution: The solution was to cache the streaming connection so they can be reused. This refactoring dropped the number of created connections by 10 times.

Improving code architecture

The codebase was not well-structured, making it difficult to maintain and extend.

Solution: We refactored the codebase by extracting reusable widgets, and adopt a well-defined state management pattern.

outcome

Refactored the codebase Implemented various features such as video player and quizzes.
