What I'm looking for

I’m looking for full-time, part-time, contract, or remote opportunities where I can build clear dashboards and reports, run SQL/BI analysis, and help teams make smarter decisions with data.

I’m a results-driven Data Analyst focused on transforming complex datasets into clear, actionable insights using Excel, PostgreSQL, and Power BI. I recently completed an end-to-end e-commerce analysis of 8,000 user records—cleaning the dataset, building calculated columns, writing 15+ SQL queries (CTEs, CASE, window functions), and designing 5 interactive Power BI dashboard pages.

In my freelance roles, I turn data into measurable outcomes by building financial dashboards (P&L, balance sheets, cash flow) and delivering budget variance analysis with drill-downs. I also develop forecasting models using historical trends and present data in clear, decision-ready formats for non-technical stakeholders, with a strong emphasis on data cleaning, storytelling, and funnel/segmentation analysis.
