What I'm looking for

I am seeking a data-focused role where I can use visualization, BI tools, and predictive analytics to inform strategy, mentor teams, and improve data-driven decision-making.

I am a detail-oriented data analyst with three years of hands-on experience applying data visualization, BI development, and predictive analytics to drive business decisions.

At Rafiki Wa Maeendeleo Trust I designed and automated SQL dashboards and built Tableau reports that improved reporting efficiency by 30% and supported a 15% improvement in sales strategy.

My background includes ICT support, training, and systems administration roles where I implemented e-learning platforms, maintained network and hardware infrastructure, and trained staff in data management best practices.

I am proficient in Python and R for statistical analysis, Tableau and Power BI for visualization, and Excel for advanced analytics; I focus on data quality, validation, and clear storytelling to inform executive decisions.
