I’m a Data Engineer with 8+ years of experience building scalable data platforms and cloud-native ETL/ELT pipelines for financial systems. I specialize in Snowflake, PySpark, and distributed data processing, and I’m driven by measurable improvements in reliability, performance, and operational efficiency.

At LTIMindtree, I helped design architecture and migrate 180+ datamarts from Sybase IQ to Snowflake—eliminating production instability and boosting platform reliability. I rebuilt 150+ ETL workflows into Snowpark-based ELT pipelines, cutting runtime by 30–40%, and created a metadata-driven ingestion framework that reduced onboarding time by 50%.

I also focused deeply on performance and quality: optimizing Snowflake with clustering and warehouse tuning improved query performance by 35%, while data quality pipelines reduced production incidents by 45%. I designed archival strategies for 5TB+ of historical data for regulatory compliance, automated financial reporting to reduce manual effort by 80%, and mentored junior engineers on the new Snowflake-based Data Warehousing architecture.
