Things I've built, and the thinking behind them.
A maths tutor for Tanzanian Form 4 students, living on WhatsApp: send a NECTA question, get a step-by-step solution narrated in Swahili with an animation that draws the working out.
A five-minute anagram hunt: one long word, race the clock to dig out every smaller word hiding inside it, then read the ones you missed.
A rent-prediction model for Dar es Salaam, told as a data essay, with interactive SHAP & feature-importance charts and a live rent calculator.
A Swahili-first trainer for all 170 Tanzanian (SADC) road signs: quiz drills, XP & levels, fully offline.

A Monte Carlo simulator that projects any nation's run to the trophy, or whether two teams' paths collide.
