About

I’m a Data Engineer with 5+ years of experience across Snowflake, Databricks, Azure, SQL, and Python. I focus on building scalable foundations that AI products can trust.

My edge is bridging both worlds: deep data engineering rigor and practical AI implementation.

AI Signature

I don’t just use AI. I architect the data contracts, retrieval logic, and automation loops that let AI think with context.

  • Designing AI-ready lakehouse models
  • Building retrieval and decision pipelines
  • Automating reporting with LLM-powered workflows
