Prioritize projects that:
1. Solve real problems
2. Show technical depth
3. Demonstrate business impact
4. Use modern technologies
5. Include full lifecycle (design → deploy)
6. Have live demos
7. Are well-documented

// Case Study Structure
Title: Scaling E-commerce Platform to 100k Users

Context:
- Company: TechStartup
- Timeline: 6 months
- Team: 4 developers
- Your Role: Lead Developer

Challenge:
The platform was experiencing 5+ second load times
and frequent crashes during peak traffic. Conversion
rates were dropping, and customer complaints increased.

Solution:
1. Implemented Redis caching layer
2. Optimized database queries (added indexes, rewrote N+1 queries)
3. Set up CDN for static assets
4. Implemented database read replicas
5. Added rate limiting

Technical Details:
- Used Redis for session storage and query caching
- Implemented lazy loading for images
- Configured PostgreSQL read replicas
- Set up Cloudflare CDN
- Built custom rate limiter using Redis

Results:
- Load time: 5s → 0.8s (84% improvement)
- Uptime: 99.5% → 99.95%
- Conversion rate: +18%
- Customer complaints: -65%
- Infrastructure costs: -30% (after optimization)

Reflection:
If I could do it again, I would:
- Implement caching earlier
- Set up monitoring from day one
- Involve the team in architectural decisions

Design guidelines:
✓ Simple, clean layout
✓ Consistent color scheme (2-3 colors max)
✓ Professional typography (readable fonts)
✓ Plenty of white space
✓ Clear visual hierarchy
✓ Mobile-first responsive design
✓ Dark mode option
✓ Accessible color contrasts
