Zeb Piasecki

Zebulon developed production-ready features across several Cloudflare repositories, focusing on frontend scaffolding, observability, and analytics. In cloudflare/templates, Zebulon built a React Router v7 starter template with server-side rendering, TypeScript, and Tailwind CSS, enabling efficient edge-enabled frontend deployments. For cloudflare/workerd, Zebulon enhanced observability by implementing a SpanObserver for streaming tail workers and expanded analytics payload limits using C++ and distributed systems expertise. In cloudflare/agents, Zebulon introduced event-driven observability instrumentation in TypeScript, establishing a foundation for future monitoring integrations. The work demonstrated depth in system programming, performance optimization, and full stack development, addressing real-world deployment and debugging needs.
