What I'm looking for

I’m looking to build production LLM/RAG and real-time conversational AI with strong MLOps ownership—deploying, monitoring, and improving models in low-latency distributed systems across cloud platforms.

I’m a Senior AI/ML Engineer with 8+ years of experience building large-scale machine learning and LLM-based systems for production. I specialize in RAG pipelines, transformer-based NLP, and real-time conversational AI architectures—turning models into reliable, low-latency experiences.

In my recent roles, I designed and deployed real-time voice AI systems with Twilio, Deepgram (STT), and ElevenLabs (TTS), and built WebSocket-based streaming infrastructure using FastAPI microservices. I also drive MLOps end-to-end—model deployment, monitoring, and lifecycle automation—across AWS, Azure, and GCP, including HIPAA-aware workflows for healthcare automation.
