At GraphX Solutions Private Limited, I developed Python ETL automation workflows with Selenium and Playwright to extract and process data from web-based platforms. I also developed basic FastAPI endpoints and contributed to a Django portal for triggering and monitoring workflows.

At Cognizant Technology Solutions, I developed and optimized Snowflake queries and dimensional data models for reporting and analytics. I transformed and validated datasets containing 1M+ records and investigated data quality issues affecting reports.

In personal projects, I built an event-driven Azure Data Factory pipeline to ingest Parquet files from ADLS Gen2 and load transformed data into Azure SQL. I also built a Snowflake and dbt Core ELT pipeline with incremental loading, dimensional models, and data-quality tests.
