The Challenge & Constraints

Traditional coding tutorials are passive and disjointed. Beginners get stuck in tutorial hell because exercises lack instant visual DOM feedback, progressive difficulty gating, and motivating reward mechanics.

Engineering Solution

Designed a track-based curriculum system (HTML, CSS, JS, React, TypeScript) where lessons teach concepts and immediately drop students into an interactive split-pane editor with live rendered output, instant test verification, unlock tiers, and leaderboards.
