Data analyst specializing in Business Intelligence and Data Management, with experience in creating interactive dashboards, performance analysis, and optimizing business processes.
I help companies and startups transform their data into decisions through tools like Power BI, Google BigQuery, advanced Excel, and Python (pandas).

Executive dashboards in Power BI or Looker Studio
Simple predictive models with Python
Database cleaning and structuring
