At Zscaler, Inc., I designed and maintained 20+ Matillion and dbt pipelines processing 20M+ records in Snowflake. I also built PRISM, a LangGraph agent integrated into GitHub Actions that reviews downstream dbt dependencies and cuts review time 50–65%.

I took an agentic AI system from proof of concept to production, where it resolves 92.6% of pipeline issues. I’ve also built RAG pipelines and an NL-to-SQL assistant used by 50+ stakeholders, and developed Python API integrations with scheduled Control-M and Airflow workflows.
