## About

```text
I've built analytics solutions at Analyst Lab Africa and the University of Nairobi, turning financial, operational, and institutional data into dashboards and actionable recommendations.

I use Python, SQL, ETL pipelines, REST APIs, and Power BI to automate data processing, optimize databases, and deliver KPI tracking across large datasets. At the University of Nairobi, I improved query and dashboard performance across 500k+ records.

I've also applied machine learning and statistical analysis to warehouse inventory, clinical trial outcomes, Uber operations, and fMRI neuroimaging data, translating complex findings into clear decisions.
