React / Node Developer – Real-time Web App Prototype (Education)

I am building an educational real-time whiteboard web application prototype (Xygur Whiteboard).
I already have a working demo and UI direction. I now need an experienced React / Node developer to turn it into a stable real-time prototype that can be deployed on my own domain and tested with a small group of teachers and students.
Scope includes:
• React frontend refinement
• / NestJS backend setup
• Real-time functionality or similar)
• Basic authentication (teacher / student roles)
• Deployment on VPS (DigitalOcean / AWS)
• Clean, scalable code structure
This is a prototype for pilot testing — not a full production SaaS yet.
Ideal candidate:
• Strong experience with React + Node/NestJS
• Experience building real-time web apps
• Clear communication
• Can provide timeline + cost estimate before starting
Please include:
