01 · Context
The problem
Many quiz applications centre generic international content rather than knowledge that feels locally relevant to Zambian players.
The response
ZamTrivia packages Zambia-focused questions across ten categories with random play, timed answers, score calculation and a device-local leaderboard.
02 · Contribution

Structured packaged questions as JSON and separated UI state through ViewModels.
03 · Implemented evidence
Current
capabilities.
04 · Engineering
Hard parts,
clear decisions.
Quiz state across many paths
Timer expiry, incorrect attempts, skips and replaying skipped questions all needed to advance consistently without losing the final score.
05 · Reflection
What I learned
Public Kotlin source verified: ViewBinding, ViewModels, timer logic, category data, skip flow and SharedPreferences leaderboard are present.
