Story arc

How this shipped

Exploring the boundaries of artificial intelligenceThree beats: what pressed against the work, how the stack answered, and what changed once it was live.

I · Constraint

The brief

Creating an engaging financial education platform that actually helps users retain knowledge long-term, with full WCAG 2.1 AA accessibility compliance.

II · Build

The craft

Implemented the SM-2 spaced repetition algorithm to schedule review cycles. Built 30+ interactive calculators, AI-powered coaching, and gamification elements. Major refactor removed 43K lines of dead code, consolidated duplicates, and cleaned up types for long-term maintainability.

III · Proof

What moved after launch

SM-2 spaced repetition scheduling for review intervals. WCAG 2.1 AA compliant for full accessibility. 43K-line refactor proves commitment to code quality at scale.
