Profile Summary

A seasoned Public Health Data Analyst with an MSc in Biostatistics and over 12 years of experience transforming complex data into actionable public health insights.

My expertise lies in the complete data lifecycle: from meticulous data wrangling and advanced statistical analysis to creating compelling visualizations and interactive dashboards with R/Shiny and Power BI. Beyond my technical skills, I am a passionate educator and an expert in capacity-building, having designed and delivered professional training on R and STATA.
