I'm Timothy Maina — a Data Analyst who bridges the gap between raw numbers and strategic clarity. I surface the patterns that matter, build the dashboards that inform, and train the models that predict — so teams can stop guessing and start deciding with confidence.
What I Do
Cleaning, exploring, and modelling datasets to surface trends and answer the business questions that actually matter.
Building interactive dashboards that give stakeholders a clear, real-time view of performance without needing to ask for a report.
Training and evaluating predictive models — from customer churn to fraud detection — with a focus on results non-technical stakeholders can act on.
Selected Work
Real problems. Real data. Real outcomes. Explore the case studies — or run a live model simulation.
Predicting logistics delivery delays using operational, driver, and environmental signals to reduce downtime and improve routing efficiency.
An end-to-end churn prediction system combining RFM feature engineering with machine learning to flag at-risk customers before they leave.
A behavioural ML pipeline identifying fraudulent transactions by analysing velocity patterns, device signals, and time anomalies — visualised in a Tableau command centre.
