Full-stack and AI engineer, 3 years shipping to production at an EV-charging platform used by 50k+ drivers - LLM features, tool-using agents, Node/TypeScript services, Postgres, and the operational side of keeping them correct. IIT Kharagpur, 2023.

Recent: a WhatsApp AI receptionist running live - Cloud API webhook, an agent that answers from the business's own content, captures leads and books appointments, with a clean human handover. https://brightsmile-whatsapp-agent.vercel.app

The work I am best at is the part after the demo: idempotency so a redelivered webhook does not double-book, durable records written before any external write, and evals on an agent's decisions rather than eyeballing a few transcripts.

Open to full-time roles and to contract work (part-time, IST evenings and weekends).
