Mpho Mpepeto
@mphompepeto
I turn operational, financial, and AI-training data into accurate, reproducible analytical workflows.
South AfricaWhat I'm looking for
I've supported AI training at RWS by annotating, validating, and quality-checking datasets for NLP and computer vision workflows, identifying edge cases and inconsistencies that affect model accuracy. At JC Kidz Educare, I built Excel-based systems and an income-and-expenditure dashboard, automating monthly reconciliations and reporting to reduce manual work by 70% and improve accuracy by 90%.
My finance degree from UCT and machine-learning volatility-forecasting thesis ground my work in statistics, econometrics, financial analysis, and clear documentation. I enjoy turning business requirements into structured, repeatable data processes using Excel, SQL, Power BI, Tableau, Python, and R.
