I've worked on real-time voice AI systems, integrating speech transcription, streaming LLM responses, and text-to-speech pipelines. I've also built AI agent-assist capabilities, RAG-based enterprise knowledge pipelines, and event-driven integrations.
My backend experience includes designing asynchronous processing systems, microservices, distributed workloads, and optimizing Node.js concurrency using Cluster and Worker Threads, improving request-handling throughput by 40%. I've also implemented production observability with Grafana and Loki, reducing issue-resolution time by 80%.
