Skill-Swap: Real-time P2P Platform

[Node.js][Express][MongoDB][Socket.io][WebRTC]

Learners lack affordable, real-time interactive platforms to exchange skills directly with peers without intermediaries.

Created a real-time platform facilitating direct P2P connections via WebRTC video calls and low-latency Socket.io messaging.

Decision: WebRTC chosen for near-zero latency video calls avoiding expensive media server costs.
Decision: MongoDB (NoSQL) for flexible user profile schemas and skill tags.
Decision: Socket.io rooms used for isolating chat sessions and whiteboard events.

! WARNING: NAT Traversal: Configured STUN/TURN servers to allow connections across different networks.

! WARNING: State Synchronization: Managed collaborative whiteboard state using event broadcasting to ensure all peers see the same drawing.
