Data Engineer at Hexaware Technologies building Azure Databricks pipelines processing 10M+ records daily.

At Hexaware Technologies, I design Azure Databricks pipelines using PySpark, SQL, and Delta Lake. They process 10M+ records daily across enterprise data sources.

I also developed batch and near-real-time ETL/ELT pipelines with Azure Data Factory and Databricks, reducing pipeline execution time by 40%. I migrated on-premises ETL workloads to an Azure Databricks Data Lakehouse, reducing infrastructure costs by 30%.

Before my current Data Engineer role, I worked as a Data Analyst at Hexaware Technologies, developing predictive models and statistical analyses. I also designed Tableau and Power BI dashboards for business and operational reporting.

Earlier, as an RPA Developer at Hewlett-Packard Enterprise, I developed and deployed UiPath workflows and provided production support. My projects include a retail data lakehouse and a real-time healthcare analytics platform.
