Worked on enhancing the reliability of task scheduling in the App-vNext/Polly repository by addressing a deadlock issue within the ScheduledTaskExecutor. Tackled the problem by implementing asynchronous task continuations in C#, which prevented inline continuation deadlocks and improved throughput under high concurrency. Added comprehensive regression tests to ensure that future changes would not reintroduce similar deadlock scenarios, thereby strengthening the system’s stability. Focused on backend development and leveraged asynchronous programming techniques alongside unit testing to deliver a robust solution. This work contributed to more resilient task scheduling, reducing operational risk and supporting smoother execution of concurrent workloads in production environments.
