Where financial precision
meets data intelligence

I'm a Business and Finance Analyst with 8+ years of accounting and finance experience across six professional roles — spanning payroll, accounting, finance analysis, revenue analytics, operations, and business analysis. I transform complex numbers into clear reporting, actionable insights, and measurable business outcomes.

My academic foundation spans a National Diploma in Accounting (Masvingo Polytechnic, Zimbabwe), a BCom Honours in Accounting and Master of Commerce (Midlands State University, Zimbabwe), and an MBA in Business Analytics at Clarkson University, New York.

I combine deep accounting rigour with modern machine learning — from predicting diabetes outcomes in 100,000 patient records to building payroll audit pipelines that catch what others miss. Four qualifications, six roles, one mission.
