• Build and optimise async, event-driven architectures using queues and pub/sub.
• Develop and maintain real-time systems using WebSockets and WebRTC.
• Implement and optimise audio/video workflows (processing, analysis, feature extraction).
• Work with Redis, MongoDB, and caching layers in distributed setups.
• Ensure services are scalable, reliable, observable (logging, tracing, metrics).
• Collaborate with AI, DevOps, frontend, and product teams to deliver end-to-end features.
