Andy Hadulo

I'm completing a BSc in Data Science and Analytics at USIU-Africa, where I've applied statistics, machine learning, database systems, big-data analytics, and Power BI to real-world datasets.

At Northum Tech, I contributed to data-driven software projects using Python, data analysis, machine learning, and web technologies. I supported data preparation, testing, troubleshooting, and delivery with developers and team members.

I've built projects spanning spatial econometrics, crop prediction, loan eligibility, energy logistics, and computer vision. My Nairobi technology-adoption analysis compared OLS, SAR, and SEM models, identifying SEM as the best-performing approach through spatial autocorrelation diagnostics.

In computer vision, I built pet skin-disease classifiers and fine-tuned EfficientNet-B0 to reach 74.6% test accuracy and 0.69 macro F1, then deployed it in Gradio for feedback-driven image collection. I enjoy using machine learning, geospatial analytics, and business intelligence to support practical, data-driven decisions.
