About the service
I embed Google Docs-style collaborative editing into finished products and implement it end-to-end, not as a demo that you'll have to complete yourselves. When several people open the same document, board, or form, they should see each other's edits character-by-character, observe cursor and selection movements, and not lose a single keystroke because two people are typing simultaneously. This is the layer I add: a conflict-free synchronization engine on top of your current stack, tied to your data model, authorization, and access rights, so everything feels like a native part of the product, not a widget glued on the side.
Inside, I work with CRDT and operational transformation approaches, most often through the Yjs ecosystem, because it provides mature merge semantics, an awareness mechanism for presence and cursors, and a transport-agnostic architecture: it works equally well over WebSocket, WebRTC, or a message broker. I handle the complex parts where such projects usually get stuck: offline editing with clean consistency when the device returns to the network, garbage collection and document snapshots so history doesn't grow infinitely, undo and redo actions that account for other participants' edits, and a storage layer that survives restarts and horizontal scaling. Presence, typing indicators, comment threads, and mentions come as part of the same model, not as separate fragile features.
You get a working integration, not a prototype. I tie the collaboration model to your editor — whether it's rich text, canvas, table grid, or structured JSON form — and cover it with tests for concurrent edits and network breaks. I document the protocol, scaling scheme, and failure scenarios so your team can maintain it further. The price and timeline below are a realistic starting point for the first collaborative surface; large implementations across multiple document types I estimate separately.
