About


My name is Jerry. In coincidence, I transitioned from the field of Western Literature to software engineering, embarking on a journey to become an engineer.

I hold a Master's in Network Learning Technology from National Central University, and recently served as a UEFI Firmware Developer at Pegatron Corporation — writing, testing, and debugging low-level firmware.

Before that, I spent nearly two years managing the Cool English educational platform at NTNU, where our team grew it to over 1 million registered users. I also built Python automation tools that cut administrative workload by 80%, turning hours of manual work into one-line commands.

Today, I stay sharp through consistent algorithm practice and continue pushing myself to understand more new technology and tools.
