Hellen Diana Macharia

I am a Junior Data Scientist with hands-on experience in Python, machine learning, and AI-driven solution development, complemented by a strong background in accounting and tax compliance. I build end-to-end ML systems and NLP-based agents, perform data cleaning, feature engineering, and model evaluation, and translate analytical findings into actionable business insights.

I have applied my skills to real-world projects—customer churn prediction, a Kenya Constitution AI agent, and a Type 2 diabetes detection system—while supporting regulatory reporting and data-driven process improvements during internships and accounting roles. I am highly adaptable, detail-oriented, and committed to continuous learning and practical impact.
