During June 2025, Ricea focused on improving WebSocket streaming stability in the mozilla/gecko-dev repository by addressing a crash triggered by garbage collection during pending writes. Using JavaScript and Web Platform Tests, Ricea developed a targeted regression test to reliably reproduce a DCHECK failure in WebSocketChannelImpl::OnWritable(), enabling precise diagnosis and prevention of this edge-case bug. The solution involved test-driven validation linked to a specific commit, ensuring the fix was robust and verifiable. This work enhanced the reliability of real-time web applications, demonstrated strong skills in JavaScript testing and WebSockets, and reflected careful attention to cross-repository collaboration and automation.
