01 / / the problem
Most "real-time" features on Upwork proposals are actually basic websocket chat. True collaborative editing with conflict resolution is meaningfully harder and pays accordingly.
02 / / what i built
→Concurrent editing with no conflicts
→Live cursor positions and selections per user
→Presence indicators with avatars
→Connection status (online/syncing/offline)
→Anonymous mode for instant demo participation
→Document sharing via link
→Recent edits sidebar with attribution
03 / / how i built it
Yjs
Battle-tested CRDT library, used by Notion and Linear
Tiptap
ProseMirror editor with first-class Yjs integration
y-websocket
Standard transport for Yjs sync
Redis pub/sub
Horizontal scale path for websocket servers
