About Jaysri

Overview:
I help businesses stop fighting with messy, slow, or broken data — and turn it into clean pipelines and dashboards people actually trust.
Over 10+ years, I've worked across the Microsoft/Azure data stack — building and maintaining ETL pipelines, migrating and optimizing SQL databases, and designing Power BI dashboards used by real teams to make daily decisions.
What I bring:

End-to-end ETL development using SSIS and Azure Data Factory — from raw source data to clean, production-ready pipelines
Strong SQL skills for data modeling, query optimization, and troubleshooting slow or broken pipelines
Power BI dashboard design — not just charts, but dashboards built around what decision-makers actually need to see
Experience working with retail, finance, logistics, Banking and Healthcare.
Comfortable stepping into existing systems, understanding legacy pipelines quickly, and fixing what's broken without a long ramp-up time
