About me

I work at the intersection of predictive modelling, impact evaluation, research and development. Over the last 6 years, I've designed and deployed production-grade ML systems, automated ETL pipelines, and interactive dashboards used by stakeholders including government ministries (MAAIF), international NGOs, and research institutions across East Africa.

At MAAIF / Makerere University, I developed prediction models for the Vanilla value chain that integrated NASA POWER satellite data with local ground-truth measurements — achieving a 30% improvement in forecast accuracy. I presented these findings to MAAIF and stakeholders across public and private sectors.

At USAID SITES (DLH Corp & SSS Inc.), I led impact evaluations and built automated analytics systems that compressed evaluation cycles from 6 weeks to under 10 days — a 85% efficiency gain.

I hold an M.Sc. in Data Science from MAHE India and am certified in PMP, Power BI, SAS Statistics, and Tableau. Based in Kampala and available for remote and international roles.
