What I'm looking for

I want to use my Power BI and SQL expertise to design optimized data models and dashboards that deliver actionable insights, ensure secure KPI reporting, and support strategic decisions in a growth-oriented organization.

I’m a Power BI Developer with 11.5 years of overall IT experience and 4.9 years of specialized expertise in Power BI and SQL. I design and optimize data models, dashboards, and reports that drive actionable insights and support strategic decision-making.

In my day-to-day work, I build end-to-end BI solutions using Power BI Desktop and Power BI Service, leveraging DAX, Power Query, and strong data visualization practices. I focus on robust semantic models, reusable datasets, and efficient ETL pipelines to ensure secure, role-based reporting and reliable performance.

I also bring practical hands-on skills across SQL (joins, views, query optimization), ETL, KPI analysis, and performance tuning—plus troubleshooting to keep reporting stable. Through projects like retail, transportation/logistics, and insurance analytics, I’ve delivered interactive dashboards with drill features and automated workflows using Power Automate.
