8. Risk Assessment

8.1 Technical Risks

Map performance with large datasets

Mitigation: Implement pagination and lazy loading

Mobile device compatibility

Mitigation: Mobile-first design approach with TailwindCSS

Photo storage scalability

Mitigation: Use cloud storage service with CDN

8.2 Team Risks

Different backend experience levels

Mitigation: Pair programming and knowledge sharing sessions

Integration challenges between frontend and backend
