Senior Data Engineer at Empower building data quality and monitoring frameworks and developing PII detection with Presidio and LLMs.
IndiaWhat I'm looking for
At Empower, I’m building business campaign ETL pipelines and a firm-wide Data Load Monitoring Framework for scalable data ingestion, data quality, and governance. I’m also developing PII detection using Microsoft Presidio and LLMs.
At Deloitte India (Offices of the US), I delivered enterprise data engineering work for financial services and pharmaceutical environments, including Snowflake migrations and AWS-native data platforms.
I migrated 83 production tables from Redshift to Snowflake, reducing pipeline runtime by 67% with zero data loss. I’ve also helped reduce daily manual ETL effort from 90 minutes to 5 minutes.
My work includes building ETL pipelines with AWS Glue, Informatica IICS, PySpark, Python, and SQL. I’ve also mentored engineers and taken responsibility for critical pipelines, incident recovery, and SLA delivery.
