In November 2025, Pozen developed foundational messaging infrastructure for the coze-dev/coze-studio repository, focusing on integrating a NATS EventBus to support scalable, asynchronous communication. By leveraging Go and NATS, Pozen enabled both Core NATS and JetStream, allowing for reliable, decoupled messaging across backend services. This event-driven architecture reduced system coupling and improved throughput and fault tolerance for critical workflows. Pozen also updated documentation to guide integration and usage, ensuring maintainability and clarity for future development. The work demonstrated depth in backend development and cross-team collaboration, laying essential groundwork for future event-driven features without introducing new bugs during the period.
