About Me

Data Specialist with
Enterprise-Scale Impact

I'm a SQL Developer / MSBI Developer at Tata Consultancy Services (TCS), currently serving AIG (American International Group) — one of the world's largest insurance companies — from Mumbai, India.

Over the past 3+ years, I've built and optimized mission-critical data infrastructure in the Banking, Finance & Insurance domain — processing millions of records with high accuracy and zero tolerance for failure.

My expertise spans the full data pipeline lifecycle: from writing complex T-SQL and tuning sluggish queries, to designing SSIS ETL packages, building Azure Data Factory cloud pipelines, and delivering Power BI dashboards that leadership actually uses to make decisions.

I don't just write SQL — I design systems that perform at scale, migrate reliably to cloud, and tell clear stories through data.
