Umuhanda

Overview

Umuhanda helps people in Rwanda prepare for the provisional driving licence exam. It has the full question bank in Kinyarwanda, English and French, a practice mode with explanations, and a timed mock exam.

The problem

Most learners study from printed booklets or scattered PDFs, often in a language they’re less comfortable reading. The official exam is timed, so practising without a clock leaves people unprepared. Many learners also study on cheap phones with patchy data.

What I did

• Built a trilingual question bank of road rules and road signs, with Kinyarwanda as the default.
• Built an untimed practice mode with instant feedback, and a 20-minute exam that mirrors the real one.
• Wrote client-side search with stemming and question-number lookup, with no server round trips.
• Made it an installable PWA that works offline, with an optional road-sign image pack.
• Pre-rendered every page with structured data and hreflang so each language ranks on its own.

Outcome

Umuhanda is live with 198 questions in three languages, all usable offline. It taught me how much of a site’s quality lives in the unglamorous parts: redirects, caching headers, and keeping three translations of every question in sync.
