I started experimenting, making models, talking to experts in the field, taking their feedback, and refining, and I kept on refining and refining for nights and weekends for over five years.
Saya mulai mencoba, membuat model, meminta bantuan para ahli di bidang masing-masing dan mulai menyaring, dan saya terus menyaring sepanjang malam dan akhir pekan selama 5 tahun.
