vivdbe Real-Time Calling and Communication System

Real-time communication requires extremely low latency, reliable signaling, and stable session handling, especially under unstable network conditions.

Implemented a WebRTC-based media layer combined with WebSocket signaling, supported by robust lifecycle management and error-handling patterns to ensure smooth real-time communication.

• Implemented real-time audio and video communication using native WebRTC
• Built WebSocket-based signaling for call setup, negotiation, and reconnection
• Delivered low-latency call experiences with stable session lifecycle management
• Handled edge cases such as reconnections, network drops, and state recovery
• Designed maintainable UI states for call flows and real-time user feedback

Enabled reliable, low-latency audio and video communication suitable for real-time collaboration use cases, improving call stability, reducing reconnection issues, and delivering a smoother user experience under varying network conditions.
