IndiaWhat I'm looking for
I’m a Data Engineer with 6 years of experience in ETL development, data warehousing, and data quality frameworks, focused on improving production reliability and reporting outcomes. At Infosys Private Limited, I developed a config-driven data quality framework on AWS Redshift, reducing manual validation effort by 40% while improving alert triage by 50% and lowering false positives by 35%.
I’ve repeatedly driven measurable performance gains by diagnosing and resolving critical ETL failures—rewriting SQL to cut recurring failures by 30% and accelerating processing by 25%. I also built operational dashboards in Power BI and automated 20+ quality checks and reporting tasks using Amazon Q and scripting, saving 8 hours of manual effort weekly.
