At Cognizant Technology Solutions, I develop data transformation and validation workflows with SQL, Python, and PySpark using Databricks and Azure.
For my Bike Data Lakehouse project, I built a batch lakehouse with Bronze, Silver, and Gold layers, integrating six CRM and ERP datasets through reusable PySpark transformations.
I processed and validated 18,000+ Silver-layer records and approximately 79,000 Gold-layer rows, and configured Databricks Jobs for pipeline orchestration. I also hold Databricks Certified Data Engineer Associate and Microsoft Certified: Azure Data Fundamentals certifications.
