Data Analyst & Business Intelligence Specialist

I help businesses turn complex data into clear insights using Power BI, SQL, Excel and Python.

About Me

Hey, I’m David Otewa, a Data Analyst and Business Intelligence Specialist with a Bachelor’s and Master’s degree in Computer Science. I enjoy taking messy, complex data, cleaning it up, digging into the details, and turning it into clear insights that people and businesses can actually use.
 

I work with Power BI, SQL, Excel, Python, and other analytics tools to build dashboards, analyze performance, automate reporting, and uncover patterns that support better decisions. One project I’m particularly proud of is a machine learning model I built to help students in Kenya identify suitable vocational programs based on their needs.


What I enjoy most is solving real problems with data. Whether I’m investigating why performance has changed, building an interactive dashboard, improving a reporting workflow, or experimenting with a new analytics tool, my goal is simple: turn data into something useful and actionable.
