Monicah WairiaBased in Kenya
I’m a data scientist and BI consultant with 4+ years of hands-on experience across finance, healthcare, retail, and government. I’ve delivered 50+ end-to-end analytics projects, built automated Python and SQL pipelines that cut turnaround time by 40%, and uncovered a 15% revenue reporting discrepancy during a public-sector budget audit. Today I develop quantitative trading strategies as a research consultant on WorldQuant’s platform. I coach candidates for data analyst, BI, and data science interviews. I focus on SQL and Python problems, statistics and regression, dashboarding with Power BI and Tableau, and explaining your analysis clearly to non-technical interviewers. In sessions, I run realistic mock interviews, give direct feedback, and help you structure answers you can repeat under pressure. Best for candidates targeting analyst, BI, and entry- to mid-level data science roles who want practical, honest feedback.
