🚀 Next Steps

Testing di production environment
User feedback collection
Performance optimization if needed
Scale infrastructure untuk load
Continuous monitoring & maintenance

📞 Catatan Penting

Prinsip Pengembangan (DRY - Don't Repeat Yourself)

❌ JANGAN: Buat ulang code dari awal
✅ LAKUKAN: Kembangkan yang sudah ada
✅ LAKUKAN: Fix bug tanpa mengubah logic
✅ LAKUKAN: Reuse module & function
✅ LAKUKAN: Dokumentasi perubahan dengan jelas

Untuk Koordinat Privasi

📍 Data awal tetap dari GPS
