What I'm looking for

I'm looking to build production AI systems where I can own retrieval, agent design, evaluation, deployment, and monitoring end to end, with opportunities to solve high-scale, measurable product problems.

I've built production LLM, RAG, and multi-agent systems for Arivihan Technologies, serving 120K+ students monthly. I replaced manual doubt resolution with a six-agent tutoring system that reduced human escalations from 18% to 6%.

I design retrieval, evaluation, deployment, and monitoring end to end. At Arivihan, I built memory and serving systems with FastAPI, Redis, DynamoDB, and SQS that sustained 1.2K requests per second at p99 850ms.

Previously at InfraDock AI and UnifyApps, I built document-ingestion, Graph RAG, and enterprise search systems across PDFs, Excel files, images, and 20+ connectors. My work improved retrieval accuracy, reduced query latency, and made over 100K enterprise documents searchable.

I'm also interested in reliable agentic workflows, having built a LangGraph question generator with a 96% valid-plan rate and deployed vision-based terrain navigation for a Unitree Go2 at IIT Kanpur.
