As a Data Analyst / Business Intelligence Analyst at Freelance / Nairobi, Kenya, I clean and analyze operational and market datasets with Excel, SQL, and Power BI. I turn raw data into reports and dashboards that help clients track KPIs and make evidence-based decisions, contributing to revenue improvements of up to 40%.
At Pareto AI, I evaluated AI-generated outputs, analyzed review data for recurring patterns, and documented findings to support model quality improvements. I shared structured recommendations with research teams remotely.
In my projects, I built a Python bank customer churn prediction model that achieved 87.9% accuracy. I also developed a resume parser that stores extracted information in SQLite, and collaborated on a song recommendation system using K-Means clustering and cosine similarity.
