About the service
I am a business intelligence analyst and I help companies see what's really happening with their numbers. My main work is building interactive dashboards in Power BI and Tableau that answer the questions that really matter to leaders and teams: how revenue is changing, where margin is leaking, which cohorts are leaving and whether we're on track for this month. I don't just draw pretty charts: I start with your business questions, understand the data sources behind them and design a model that gives fast and stable answers instead of another table nobody trusts.
Behind every good dashboard lies a reliable data model, and that's where I spend most of my effort. I build neat star-schema models, write DAX measures for Power BI and calculated fields for Tableau, I handle the ETL preparation that quietly needs to happen for almost any report: merging extracts, cleaning dirty columns, removing duplicates, building date tables and hierarchies. I care about correctness and speed, so measures align with your financial numbers and pages stay responsive even on large volumes. If something looks suspicious, I dig into the model rather than masking the problem on the chart itself.
I usually work with marketing, sales, finance and operations teams who have data but no clear picture from it. You can give me raw extracts, a database connection or a rough sketch of the report you dream about — and I'll turn it into a maintainable BI product with documented measures, sensible filters and drill-down, with a layout that colleagues read without instructions. I'm ready to build one focused dashboard or a full set of reports and I'll explain each calculation so the result is yours and trustworthy.
