What I'm looking for

I’m looking to help teams make faster, better decisions with clean data, strong statistical analysis, and Power BI dashboards. I want to automate reporting, optimize processes, and deliver actionable insights through SQL and Python—while collaborating across departments.

I’m a dynamic, results-driven Senior Data Analyst with a desire to take on new challenges, turning complex data into actionable insights for strategic business decision making. At Steelwool Africa LTD, I develop and implement data collection procedures and automated reporting systems that improve operational efficiency.

I use advanced SQL queries and Python for analysis, statistical analysis, predictive modelling, and A/B testing—then translate results into clear dashboards and KPI tracking with Power BI. I’ve achieved a 30% reduction in reporting time, 25% improved data accuracy through validation checks, and 40% faster insights via Power BI dashboards while ensuring data integrity and quality assurance.
