Senior Data Scientist and retail measurement expert driving actionable analytics and product enhancements.
KenyaWhat I'm looking for
I am a results-driven senior data scientist with 7+ years delivering retail measurement and methodological solutions across East and Central Africa. I combine strong statistical foundations with practical product design to solve large-scale consumer data challenges.
At NielsenIQ I led sample design, universe estimation and questionnaire design with under 1% QE and 98% on-time delivery, and drove standardized tool deployment and automation across markets. I have a track record of delivering revenue-impacting solutions and cost savings through methodological improvements and product enhancements.
As a mentor and trainer, I develop team capabilities in R, tidyverse, visualization and survey methodologies, and have trained field teams on mobile data collection and quality assurance. I also freelance as a data consultant and trainer, helping clients apply clustering and regression to drive targeted marketing and measurable sales growth.
I am skilled in R, Python (basic), SQL, RShiny, Spotfire, QGIS, Tableau and Excel, and I look for roles where I can lead analytics product design, automate processes, and collaborate cross-functionally to scale measurement solutions.
