Le Vy
About this gig
Need live updates, chat, or notifications in your web app? I implement real-time features using SignalR and WebSockets, backed by Redis Pub/Sub for scale.
I've built real-time messaging (chat, online status, seen/unseen) and live assessment systems used by tens of thousands of concurrent users.
Send me a short brief of what you need and I'll confirm scope before you order.

FAQ
What information do you need before starting?
Access to your codebase (GitHub/GitLab), and a short description of which real-time feature you want (chat, notifications, live dashboard, etc). I'll confirm feasibility and scope before you order.
Do you support both SignalR and plain WebSockets?
Yes. I mainly use SignalR for .NET apps, but I also work directly with raw WebSockets, Redis Pub/Sub, and Kafka when you need more control or cross-platform support.
