Hi, I’m Alexandros Michael, a BI Data Analyst based in Athens, Greece. I design and optimize BI systems to deliver actionable insights, combining strong ETL skills, data warehousing, and tools like Tableau, Looker, and dbt. I’m passionate about automating workflows, maintaining data quality, and turning business requirements into practical technical solutions that support data-driven decision making. In my recent roles at Data Strategies, Semrush, Celesta, Raycap, and XM, I’ve built scalable BI infrastructures, migrated to Looker from ChartIO, established governance processes, and developed predictive models to forecast engagement and retention. I’ve also led cost-monitoring initiatives that reduced department costs by about 20%, and I enjoy collaborating with stakeholders to boost efficiency and ROI through analytics, dashboards, and proactive data governance.…Hi, I’m Alexandros Michael, a BI Data Analyst based in Athens, Greece.
