Varchasv Hoon

Data Engineer with 1.7 years of experience building data pipelines and automation on a global enterprise account. My core stack is PySpark, SQL, Databricks, Delta Lake and AWS, and I hold the Databricks Certified Associate Developer for Apache Spark (Python) certification. I cut a SQL query's runtime from 84 seconds to 4 seconds by removing duplicate rows that the original query was carrying through, and I've automated ETL and KPI reporting with Python and Pandas. Outside work, I've built end-to-end Medallion Architecture pipelines on Databricks, including one on 21 years of RBI banking NPA data across 200+ banks and another on air quality data from 490 CPCB stations, using Delta Lake, Unity Catalog and Spark Declarative Pipelines. I also contributed to an AI companion tool on an enterprise GPT platform. I'm based in Noida and looking for data engineering roles across the NCR.
