Work Experience
React Developer
2024 - PRESENT
Outspeed (formerly Adapt Research, Inc.)
- Re-architected and delivered a client-side real-time communication SDK supporting WebRTC and WebSocket streaming, enabling flexible deployment across diverse network conditions.
- Reduced dependency on WebRTC by building a WebSocket-based communication stack (connection, media, and data channels), improving adaptability in constrained environments.
- Enabled reliable audio/video streaming in low-resource scenarios by implementing advanced signaling logic, including SDP manipulation and dynamic transceiver configuration.
- Improved stability of the real-time media pipeline by refactoring the connection lifecycle and centralizing message handling, reducing streaming and event inconsistencies.
- Accelerated cross-platform development by designing a monorepo architecture and building shared core modules for web and mobile SDKs.
- Simplified front-end integration by developing React and React Native SDK layers with reusable hooks and components for media handling and visualization.
- Reduced onboarding friction for developers by creating comprehensive documentation and interactive playgrounds for real-time communication use cases.
