Worked on enhancing reliability and maintainability in the ArmoniK.Core repository by overhauling task termination and error handling mechanisms. Replaced the previous abort-based approach with explicit task and result termination on crashes, improving error visibility and clarifying task lifecycle semantics. Automated the cleanup of subtasks from crashed tasks to prevent orphaned work and resource leaks, directly addressing gaps in failure scenario handling. Focused on backend development using C# and asynchronous programming, with careful attention to concurrency control and robust error handling. These changes led to more predictable job processing, reduced cascading failures, and improved observability into crash conditions within the system.
