I build enterprise Power BI reporting solutions, from semantic models and DAX to production dashboards.
GreeceWhat I'm looking for
At Accenture Greece, I build end-to-end Power BI solutions for telecommunications, public sector, and mining clients. I design semantic models, DAX measures, and production-ready dashboards that make operational and infrastructure KPIs accessible in real time.
I’ve served as the sole BI analyst on a national fiber network reporting solution and independently audited 600 Power BI reports for the Greek government, identifying modeling, logic, visual, and performance issues. I also delivered matched Power BI and Excel reporting for a global precious metals mining client, from requirements through stakeholder sign-off.
Previously, I used SQL, Python, and Excel to extract, validate, and analyze large financial datasets for banking and consulting engagements. I’m expanding into data engineering and cloud analytics through Microsoft Fabric and Azure.
