My name is Pan, ChingYa, a Catholic. I graduated
from the Taipei City University of Science and Technology Computer & Communication Engineering, ranked number 1. I earned my master degree from National Taipei University of Technology. My thesis in graduate school is "An Integrated Mattress System with Turning Over Detection and Recording Mechanism". it’s about IoT and MSP430.
I have been an Electrical Engineer for 6 years.
I am responsible for the cellular module, mobile operating system, and audio circuit design. I am very familiar with various EDA tools such as Altium Designer, Cadence, Allegro and
