📈 Key Lessons Learned
What Worked Well

✅ Monero Integration — Subaddresses work perfectly for tracking payments
✅ Smart Contract Design — OpenZeppelin provided excellent security
✅ API Structure — Clean separation of concerns (routes, controllers, models)
✅ i18n Support — Multi-language made the platform more accessible
✅ JWT Authentication — Simple and effective role management
What We'd Do Differently

🔄 Better Documentation — Swagger/OpenAPI should have been there from day one
🔄 Docker First — Containerization would have made deployment easier
🔄 Webhooks Early — Event notifications would have improved integration
