collaborative LeetCode suffering

A Chrome extension for solving LeetCode problems collaboratively, with shared presence and real-time communication. Because getting stuck is nicer when it is technically a group activity.

My very talented friend was doing this project, and I decided to join and contribute for a few months. The project is now abandoned (sadly), but the idea is still very cool, and I hope someone picks it up.

What I worked on

  1. Presence

    Authored the RFC and moved the heartbeat system from WebRTC to Firebase for one consistent view of who was actually online.

  2. Automation

    Built a GitHub Actions pipeline for tests, builds, and ESLint checks—the robotic coworker who never forgot to run them.

  3. Collaboration

    Helped make technical-interview practice feel less solitary, though the algorithms remained personally offensive.
