What I'm looking for

I'm looking to apply my business intelligence, data integrity, reporting automation, and reconciliation experience in a data-focused role where I can improve decision-making, strengthen governance, and build reliable dashboards and processes.

I've delivered business intelligence, data reconciliation, and reporting solutions across NBC Holdings, CNBC Africa, Themis Law Chambers, and Goldwood Industries. At NBC Holdings, I analyze membership data with SQL and Excel, automate executive reporting, and reduced corporate client registration processing delays by 25%.

Across regulated membership and financial-data environments, I've cleaned and validated high-volume records, reconciled premium collections, supported system migrations, and built interactive Power BI and Tableau dashboards. I bring over seven years of experience in data integrity, forecasting, database management, and cross-functional reporting.
