🏗️Business Requirements Drive Technical Architecture

Feature Request Analysis

"Can I study cards in reverse? Sometimes I want to see my native language and guess the translation, other times see the translation and guess the meaning."

— Language learning user feedback

User Value

Doubles learning effectiveness by practicing both recall directions

Business Opportunity

Premium feature to drive authentication and future monetization

Technical Challenge

Multi-layer authorization without breaking existing UX

Business Strategy Framework

Progressive enhancement:✓ Core features free
Feature teasing:✓ Show locked premium
Conversion funnel:✓ Friction → Growth
Future monetization:✓ Subscription ready

Technical Requirements Matrix

CRITICAL: No breaking changes to existing functionality
SECURITY: Multi-layer authorization (UI + Server + DB)
UX: Graceful degradation for unauthenticated users
BUSINESS: Conversion tracking and analytics

Product-Minded Developer Thinking vs Technical-Only Thinking

❌ Technical-Only Approach

  • • "How do I swap card.front and card.back?"
  • • "Where should the direction state live?"
  • • "What's the cleanest code structure?"
  • • "Should I use a toggle or radio buttons?"

✅ Business-Minded Approach

  • • "How does this drive user engagement and retention?"
  • • "What's the conversion funnel for this feature?"
  • • "How do we monetize without alienating users?"
  • • "What analytics do we need for future decisions?"
