Document synchronization
CRDT
Implemented collaborative document model. This preview has no active multi-user session; no concurrency scale is claimed.

Case study / Collaboration prototype
NexGrid
A shared coding workspace exploring CRDT synchronization, WebSocket collaboration, and code execution workflows.
Collaboration prototype
Solo project; AI-assisted development.
The idea
The problem
Concurrent edits must converge while document state and execution feedback remain understandable.
The implementation
What I built
Built a shared editing interface around CRDT synchronization, WebSocket events, and execution feedback.
- React
- JavaScript
- WebSockets
- CRDT
- Python
Features
- Edit a shared CRDT document
- Synchronize changes over WebSockets
- Inspect execution feedback
Architecture
- Browser editor and workspace.
- CRDT shared document with WebSocket synchronization.
- Separate execution and result-presentation workflow.
Engineering decisions
- Use a shared document model for concurrent changes.
- Present execution feedback separately from document synchronization.
Validation and measured results
- Source and local interface demonstrate collaborative editing and execution workflows.
- No published large-scale concurrency or latency benchmark is attached.
Limits and unfinished work
- Prototype status does not imply a hardened public code-execution service.
- Inference-gateway throughput and accelerator results do not apply to this project.
Evidence and sources
- Collaborative editor validation notes
Locally reviewed implementation; no production scale claim. The repository was not publicly accessible on 14 October 2026.
