End-to-end data-science and machine-learning projects on real public data — predictive modeling, statistical inference, forecasting, optimization, and experimentation across healthcare, energy, finance, retail, and beyond.
12-month horizon on real PEPFAR shipment records — Rwanda focus.
State-space + Fourier exog vs SARIMA on 145k hours of PJME load.
Poisson / Gamma / Tweedie GLMs on freMTPL2 with GBM challenger.
SARIMA + GBM with MinT-OLS to make item × store × week forecasts coherent.
MDP + Q-learning vs capped LP baseline on real KMPDC + SHA data; LP+equity is the deployable candidate.
Daily lake level on real Zambezi reservoir data; SARIMA wins 30-day planning (18 cm, calibrated PI).
Daily irradiance with weather covariates from NASA POWER API.
Tenure-as-time, churn-as-event; KM, Cox PH, Weibull AFT, log-rank stratification.
Daily volume forecast on top route + GBM price predictor across all routes.
Bedroom + property-type + neighborhood features on 9,607 Lagos sale listings.
Lat/lon + farm features on 931 households; same-village leakage dismantled with spatial GroupKFold.
XGBoost vs RF vs LogReg with calibration plot and retention-queue ranking.
Welch t-tests + ANOVA + OLS adjustment + Bayesian posterior on a real 3-arm trial.

Mapped against four consulting pillars: advanced analytics & modeling, visualization & reporting, AI development & automation, collaboration & governance. The Techniques and Tools below back the first two. The applied AI work, supervision, and workshops that back the other two live on the consulting page.
