Ugonna I.

Need help turning messy business data into clear dashboards, reports, and actionable insights? I help businesses analyze their data, build interactive dashboards, automate reporting, and identify the trends behind their performance using Power BI, SQL, Tableau, Excel, and Python. I can help you with: • Power BI dashboard development and DAX • Tableau dashboards and data visualization • SQL queries, CTEs, joins, window functions, and data analysis • Excel dashboards, Pivot Tables, Power Query, and XLOOKUP • Data cleaning, validation, and transformation • KPI and management reporting • Customer, sales, transaction, and operational analysis • Google BigQuery and Looker Studio analysis • Root cause and trend analysis My experience includes working with banking, payments, e-commerce, customer, and operational datasets. For example, I have: • Built Tableau dashboards for product performance, client rankings, sales opportunities, and operational KPIs • Developed SQL-based analytical reports and Power BI dashboards for transaction volumes, settlement rates, success rates, processing times, and exception trends • Performed customer funnel analysis in BigQuery and Looker Studio that identified checkout friction and contributed to a 14% increase in conversion • Built reusable SQL views and analytical datasets for recurring management reporting • Worked with stakeholders to translate business requirements into KPIs, calculations, dashboards, and actionable insights My goal isn't simply to create charts. I focus on answering the business questions behind the data and presenting the results in a way that makes decisions easier. If you have a dataset, reporting problem, or dashboard that needs improvement, send me a message with what you're trying to understand or achieve.
