KNU Link

1. Inspiration 💡 The problem you observed as a KNU student Why anonymity and swipe interface made sense The "aha moment" that led to KNU Link
2. What I Learned 📚 Detailed technical learnings with code examples:

Real-time communication with Supabase Gesture-based UI with Pointer Events (with mathematical formulas in LaTeX!) Row-Level Security challenges and solutions State persistence with localStorage Progressive Web App implementation

1. How I Built It 🔨 Architecture diagram (Mermaid) Tech stack justification table 5-day development timeline Database schema with design decisions Component architecture
2. Challenges Faced 🚧 Six major challenges with solutions:

Supabase RLS policy debugging Swipe gesture conflicts Real-time message ordering Environment variable configuration Build errors localStorage synchronization

1. Technical Insights 🧠 Performance optimization strategies Security considerations Future enhancement ideas
2. Reflection 🤔 What went well What you'd do differently Skills acquired 📐 Special Features: ✅ Mathematical formulas in LaTeX (swipe detection algorithm) ✅ Code snippets with syntax highlighting ✅ Mermaid architecture diagram ✅ Tables for tech stack comparison ✅ Emoji navigation for readability
