TanzaniaWhat I'm looking for
I’m a results-driven Data Analyst with a B.Sc. in Mathematics and Statistics and over 3 years of experience working with large datasets to support business and commercial decision-making. I specialize in statistical analysis, forecasting, A/B testing concepts, and translating complex data into actionable insights.
At Wilkudos Company Limited, I analyzed large, multi-source datasets to identify trends and performance gaps, and I prepared forecasting models and analytical reports for management. I also supported pricing, discount, and customer performance analysis, reviewed and validated reports from junior analysts, and trained analysts across Zambia, Angola, and Nigeria to strengthen data quality and reporting standards.
Earlier, as a Field Student at the Tanzania Meteorological Agency, I collected, cleaned, and analyzed meteorological and climate datasets to identify weather patterns and seasonal trends, contributing to technical reports and forecasts. I bring a high standard of professionalism, integrity, ethical awareness, and a proactive, growth-oriented mindset to every analysis and stakeholder collaboration.
