Data Analyst | Aspiring Data Scientist — Python / SQL / ML / Tableau / Power BI

Willard Odongo

I turn messy, real-world data into decisions people can trust. My work spans the full analytics lifecycle — cleaning and validating data, exploratory analysis, feature engineering, and building and evaluating machine learning models in Python — with a habit of writing findings up so a non-technical stakeholder can act on them.

About

I'm a data analyst working toward data science, currently applying data engineering and integrity thinking to production systems at Lido Nation — building validation checks, tracing root causes of data discrepancies, and translating operational data into recommendations for cross-functional teams. Outside of work I build end-to-end machine learning projects in Python: classification, regression, and statistical analysis on real datasets, documented as reproducible notebooks.
