Biography & Background

About Raj Chhapariya

AI / Data Engineer · Bengaluru, India

I am an AI / Data Engineer based in Bengaluru, India, focused on building reliable data pipelines, in-process analytical engines, and evaluated LLM systems.

My background spans Python, SQL, JavaScript, and TypeScript, with practical experience designing deterministic query guardrails and assessing LLM outputs for groundedness and citation faithfulness. Full-stack and backend development serve as supporting capabilities that allow me to take data systems from concept to production-ready interfaces.

Whether engineering hybrid retrieval-augmented generation pipelines, developing in-process columnar analytics with DuckDB, or deploying applications on Next.js and PostgreSQL, I prioritize verifiable metrics, safe execution boundaries, and reproducible results.

Engineering Philosophy

  • •Accuracy and Grounding: AI and analytical tools must verify outputs against underlying data and provide transparent citations.
  • •Safety by Architecture: Restrict execution privileges (such as read-only SQL) rather than relying on unconstrained code execution.
  • •Clarity and Maintainability: Write clear, modular code with structured Pydantic and TypeScript validation contracts.
