Worked on improving the stability of real-time voice interactions in the fishjam-cloud/web-client-sdk repository by addressing a bug in Voice Activity Detection polling. Focused on eliminating flickering of the speaking indicator and preventing stale state updates, the solution introduced an AbortController to manage polling lifecycles and added guards around asynchronous boundaries. This approach ensured that polling operations were properly canceled when React components unmounted or were disabled, reducing the risk of memory leaks and race conditions. The work was implemented using TypeScript and front end development skills, demonstrating attention to reliability and maintainability in a complex, asynchronous user interface environment.
