Expertise
Background
I'm Daniel Enantomhen — a certified Data Analyst and AI Developer based in Abuja, Nigeria. I have hands-on experience analysing and visualising data using R, Microsoft Power BI, and Excel, and I build production-ready AI tools and full-stack web applications using Claude Code and modern AI APIs.
My analytics work spans dashboard development, KPI definition, statistical analysis, time series analysis, and data visualisation — transforming complex datasets into clear, actionable business insights. I've built interactive Power BI dashboards tracking revenue performance, activation rates, and manager-level KPIs, as well as R-based regression and economic analyses on multi-decade datasets.
With a background in Materials & Production Engineering from Ambrose Alli University, I bring an engineering mindset — precise, systematic, and built to last — to every data and software project I take on.
