# Pavan Badempet on Tal

## Headline

Data Engineer \| Apache Spark, PySpark, Python & SQL \| AWS, Databricks, Snowflake \| Scalable ETL/ELT Data Pipelines

## About

I build production\-grade, scalable data pipelines that power critical business decisions in capital markets and automotive\. At TCS, I work with Nomura's capital\-markets technology team designing Spark ETL systems for trade, risk, and valuation data — processing millions of records daily across Apache Iceberg and Dremio\-backed lakehouse architecture\. I've reduced Spark batch runtimes by 30% through Catalyst execution\-plan optimization and led the migration of Spark workloads from YARN/HDFS to Kubernetes, reducing compute costs by 35% through targeted infrastructure optimization and orchestrating daily/monthly batch schedules to feed downstream ML anomaly detection models\. Previously, I developed Python\-based AWS Lambda functions for Nissan to parse, clean, and validate diagnostic logs in multiple formats \(CSV, JSON, Excel\) uploaded to S3, automating ingestion via Step Functions into Snowflake — reducing manual data preparation by 60% and QA verification cycles by 30% by achieving 90%\+ test coverage through automated testing\. My core stack: Apache Spark, PySpark, Spark SQL, Spark Structured Streaming, Python, SQL, Scala, AWS, Snowflake, Databricks, Delta Lake, Apache Iceberg, Airflow, MLflow, Kubernetes, Docker\. I'm particularly interested in distributed systems, data modeling, lakehouse architecture, performance optimization, and building tools that make data engineering teams more productive\. Open to connecting on data engineering, distributed systems, and scalable pipeline design\. Let's talk\.
