PROFILE
Kay(kéi) Sawada
Kay Sawada developed a WebSocket passthrough feature for the fastly/js-compute-runtime repository, enabling direct handoff of WebSocket connections to specified backends. This work involved designing and implementing the createWebsocketHandoff function, updating the JavaScript runtime, and ensuring robust TypeScript typings and integration tests. Kay focused on API development and WebSocket lifecycle management, producing comprehensive documentation and collaborating across teams to align backend integration and testing. The feature reduces latency and architectural complexity for real-time applications by bypassing intermediaries, supporting live data streams and communication use cases. The work demonstrated depth in C++, JavaScript, and Compute@Edge runtime engineering.
