## About

```text
At Cognizant Technology Solutions, I contributed to modernizing 30+ ETL pipelines by migrating legacy Shell, HiveQL, and SQL workloads to a metadata-driven PySpark framework. I also developed data engineering solutions for SCD Type 2 transformations, SFTP integrations, and Oracle export pipelines.

I automated migration of 1,000+ legacy scripts with a Generative AI agent, eliminating an estimated 9,500+ hours of manual effort and delivering $63K in FTE cost savings. I also contributed to workflow orchestration and pipeline runtime reductions through cluster allocation optimization and Databricks Job Clusters.

In personal projects, I built an Apache Airflow pipeline that stores trending YouTube data in PostgreSQL and a Streamlit financial assistant using the Agno framework. I hold Databricks Certified Data Engineer Associate and Databricks Certified Generative AI Engineer Associate certifications.
