Worked on the apache/pekko repository to enhance the reliability of the persistence-typed module by addressing stack overflow issues during high-volume unstashing of read-only commands. Focused on backend development using Java and Scala, the solution introduced a configurable processing path that replaces deep recursion with a tail-recursive loop, controlled by a new configuration flag. This approach improved the robustness and maintainability of the persistence layer, particularly under heavy concurrency scenarios. The work emphasized stability over new features, ensuring that the actor system could handle large bursts of unstashed commands without risking production outages or excessive stack usage.
