What I'm looking for

I’m looking to apply my advanced SQL and Power BI skills to a remote data team—automating reporting, building reliable dashboards, and using fraud analytics and problem-solving to improve risk mitigation and data quality.

I’m a detail-oriented data professional with 2+ years of experience in SQL development, data transformation, and process automation. In the financial sector, I focus on data cleaning, validation, and complex modeling, with a strong emphasis on fraud pattern analysis and scoring models.

At RECOVER, I automated reporting cycles using advanced T-SQL and Power BI data flows, reducing manual processing time while increasing data reliability. I also build internal tools with Python (Flask) and optimized SQL Server models to deliver a 360° business view, and I maintain Power BI KPI dashboards for senior leadership.
