I build reliable Power BI models and reports that drive decisions.
What I'm looking for
I'm currently building and improving data models, Power BI reports, and dashboards at Altimetrik. I improve reporting performance through DAX quality, stronger model architecture, and reliable validation against source records.
Previously at Data Rise Lab, I delivered Power BI reporting from concept to deployment, created SQL Server DWH structures, and partnered with business analysts and report users to turn reporting needs into actionable insights. I also configured Power BI Service security, gateways, and connections.
At Credit Suisse, I automated reporting by moving processes from Excel to Power BI and supported project and portfolio management stakeholders with reports, dashboards, and data delivery.
My earlier work at EY and CASAFARI combined project reporting, data quality, data-source monitoring, web scraping, Python automation, and market reporting. I enjoy transforming complex datasets into scalable, trustworthy solutions that make decision-making easier.
