What I'm looking for

I'm looking for a data-focused role where I can improve data quality, automate reporting, build dashboards, and turn complex operational or financial data into actionable insights for stakeholders.

At Old Mutual Short Term Insurance, I analyse claims and reserve data using Excel, SQL, and Power BI to support actuarial valuations, reporting, and business decisions. I produce monthly dashboards, identify data anomalies, and automate reporting processes to improve efficiency.

Previously at Black Oak Consulting, I delivered more than 20 recurring business intelligence reports using Databricks SQL, Pentaho, and MySQL. I enjoy improving data quality, translating stakeholder requirements into analytical solutions, and communicating findings to technical and business teams.
