Worked on enhancing stability in the wireapp/kalium repository by addressing a critical issue with SharedFlow coroutine lifecycle management. Focused on preventing memory leaks and reducing resource pressure, the solution introduced SupervisorJob-based lifecycle management within FlowCache and MetadataDAO, ensuring proper coroutine cancellation and eliminating zombie coroutines. This targeted fix improved the reliability and scalability of SharedFlow usage, laying a stronger foundation for future asynchronous operations. The work leveraged Kotlin, coroutines, and unit testing to deliver robust resource management. Through careful engineering, the update strengthened coroutine patterns and contributed to more stable, maintainable asynchronous programming within the codebase.
