- Use Redis for caching, sessions, pub/sub, rate limiting, queues, and other high-performance workloads.
- Build real-time features using Socket.IO and event-driven architectures.
- Develop and integrate WebRTC-based communication systems.
- Work with mediasoup and/or LiveKit for real-time audio/video communication, conferencing, streaming, or related features.
- Integrate external APIs, SDKs, authentication providers, payment systems, and other third-party services.
- Implement secure authentication, authorization, validation, rate limiting, and other application security practices.
- Identify and resolve performance bottlenecks across frontend, backend, database, and network layers.
- Write clean, maintainable, reusable, and testable code.
- Participate in code reviews and contribute to engineering standards.
- Write technical documentation and maintain clear project documentation.
- Debug production issues and contribute to incident resolution.
