About Me

Hello, I'm Stephen

…and I’m a Data Scientist, Data Analyst, and Tutor based in Nairobi, Kenya.

My work is driven by one belief: data only creates value when it solves real problems. I specialize in machine learning, statistical modeling, software development, and AI system design, building intelligent solutions that turn complex datasets into clear, practical decisions.

Currently, I work with large-scale logistics and telematics data, developing predictive models, automated dashboards, and AI-driven systems that improve operational efficiency, safety, and performance. I am also passionate about using analytics to support Kenyan dfarmers, designing data solutions that enhance productivity and financial returns.

Beyond this, I develop scalable analytics platforms that support organizations across healthcare, research, and business sectors. Skilled in Python, SQL, Power BI, and Tableau, I focus on delivering insights that are not only accurate but impactful.

My goal is to help organizations adopt smarter, data-driven strategies that foster innovation, optimization, and sustainable growth.

My Approach

How I Turn Data Into Decisions

A structured, repeatable process that delivers reliable insights every time.

01

Collection, Cleaning & Preparation

Gathering the right data from files, databases, and APIs, then cleaning and validating it while building pipelines that can run reliably without repeated manual work.

02

Analysis & Modeling

Exploring trends, patterns, and relationships using statistical tools and ML models to uncover meaningful insights.

03

Visualization & Reporting

Translating results into clear visuals and reports that help teams understand the story behind the numbers.

04

Software Development

I build apps and tools that deliver analytics in the real world dashboards, internal web apps, and API-driven systems teams can actually use.
