AI full-stack developer building RAG systems and LLM automation, including a guardrailed Indian Railways assistant.
IndiaWhat I'm looking for
At Centre for Railway Information Systems (CRIS), I architected a RAG pipeline for the Indian Railways e-Procurement System, indexing more than 400 pages of tendering documentation for bidder and vendor queries. I built a local inference pipeline with hallucination guardrails that achieved 95% answer accuracy.
In my ongoing freelance work, I build LLM-integrated automation workflows for B2B clients. I’ve also deployed API-integrated data pipelines processing more than 10,000 records and cutting manual processing effort by 90%.
As Lead Developer of AdCoherent Labs, I built an AI engine that reviews marketing assets against US financial advertising regulations and Google and Meta ad policies. I designed its PostgreSQL and pgvector data layer, including hybrid search and automated rule ingestion.
I also built Swachh Gaon, a waste-collection routing platform with real-time tracking and an AI voice assistant, and published an open-source TypeScript MCP server for LinkedIn post drafting and publishing. I’m seeking AI and full-stack engineering internships.
