Why should you work with me ?

Production AI Engineer focused on productizing Generative AI, Agentic workflows, and voice automation. I design and ship end-to-end LLM systems (RAG, vector DBs/Pinecone), agent orchestration, real-time STT/TTS, and telephony integrations (Twilio/Plivo/LiveKit) with MLOps and low-latency serving.

I’ve architected multi-tenant platforms handling thousands of daily calls and 2,000+ concurrent sessions, delivered 10.4× cold-start improvements, and cut query times by 90–95% through targeted DB & backend optimizations. I pair hands-on model work (fine-tuning, prompt engineering, tool-calling agents) with production engineering (FastAPI, PostgreSQL, CI/CD) to move prototypes into reliable, cost-efficient services.
Open to roles in GenAI productization, LLM-Ops, AI Agents & automation — happy to share demos and architecture writeups (GitHub & demo in Featured).
