B.Eng Electrical Engineering · Universitas Brawijaya

I started as an IoT & WPT enthusiast building connected systems and web interfaces — then pivoted to deep-dive into analog circuits, electromagnetics, and Wireless Power Transfer. From embedded hardware to web dashboards, I build end-to-end and never stop learning.
