FinlandWhat I'm looking for
I’m a Data Analyst with 6+ years of experience delivering data-driven solutions with Power BI, Excel, and SQL. I translate complex information—especially financial data—into clear, actionable insights that help stakeholders make faster, better decisions.
Recently, I built a complete user analytics system from scratch (data pipelines, SQL logic, and dashboards), including a Power BI user analytics dashboard adopted by external clients. I also integrate Google BigQuery into Power BI, use Power Automate for timely alerts, and embed insights for end users. Earlier, I developed and maintained 20+ Power BI dashboards, and in financial planning and reporting roles I automated report updates, improving efficiency by 50% and reducing labor by 20 hours/month while supporting forecasts and budgeting.
