DrillQuest

Language learning has a well-known retention problem — most learners drop off within the first week. DrillQuest bets that gamification mechanics (streaks, XP, achievements) meaningfully improve daily-return behavior over a plain flashcard-style app, layering those mechanics on top of core vocabulary and grammar lessons to keep learners coming back.

What I Built

• Gamification layer — streaks, XP, levels, and achievements
• Lesson engine covering vocabulary and grammar modules with progress tracking
• Mini-games reinforcing lesson content through matching and recall exercises
• Progress dashboard visualizing learning streaks and milestones

Tech Stack

• Framework: React Native
• Backend: Node.js REST API
• Database: MongoDB
• Platforms: iOS, Android

Key Decisions

• Bet on gamification mechanics (streaks, XP, achievements) over a plain flashcard-style lesson flow, based on language learning's well-known early-week drop-off problem
• Layered mini-games on top of core vocabulary/grammar modules rather than as a separate feature, so the game mechanics reinforced lesson content directly instead of existing alongside it

Outcome / Impact

Delivered an engaging learning experience with measurably higher daily-return rates than a plain flashcard approach, validating the gamification bet.
