About Me

Sancharika Debnath - Applied AI Engineer Portfolio

I'm an Applied AI Engineer based in India, focused on building LLM systems that work in production — not just in notebooks.

I've deployed offline GenAI inside DRDO's air-gapped defense network, built voice AI agents for enterprise clients, and implemented LLaMA 3 from scratch to understand transformers at the architecture level.

I care about the gap between research and deployment — and closing it.

What I can build for you

  • RAG & document intelligence systems — I build pipelines that let your product answer questions over your own data. PDFs, DOCX, databases — ingested, embedded, and queryable. Shipped for production, not just demos.
  • Voice AI agents — end-to-end conversational agents for inbound and outbound calls, with configurable tone, persona, and call flow logic. Already deployed for 3+ enterprise clients via ElevenLabs + custom orchestration.
  • LLM integration & automation — connect LLMs to your existing workflows. Prompt engineering, structured output, tool use, evaluation frameworks. I've done this in air-gapped defense environments — your stack is easier.
  • Full AI product builds — if you have an idea and need someone to own the AI layer end-to-end: architecture, backend, and deployment. I work best with early-stage startups who move fast.
  • Proven, not theoretical — every service above has a shipped project behind it. DRDO, Leapon, Giggr.

I don't pitch technology I haven't deployed.
