India

Message

At TIGERANALYTICS, I’m creating an ETL framework for a CPG company. I analyze project data against KPI requirements and load it into a Databricks medallion architecture, with data quality checks from bronze through gold.

At CELEBALTECHNOLOGIES, I created a parameterized ETL framework for an OTT platform, transforming on-premises data for downstream use. I also supported medallion-based transformations, data quality checks, data marts, and KPI-based materialized views.

For an insurance company at CELEBALTECHNOLOGIES, I migrated Informatica workflows to dbt and Databricks. I developed Databricks workflow orchestration and Delta table optimization frameworks, and hold Databricks Data Engineer Associate and Professional certifications.
