MERN + Unity Interactive Web App

I’m building a modern web platform that combines a standard MERN stack with a Unity-powered 3D experience. The React front end will behave like a smooth single-page app, while selected views load a Unity WebGL build so users can explore a mini-game or simulation without ever leaving the page... (Budget: $30 - $250 CAD, Jobs: C# Programming, JavaScript, MERN, MongoDB, Node.js, React.js, Unity, Unity 3D)
