Keith 是 iCHEF 的主任後端工程師，也曾是 PyCon APAC 2015 的主席。從 2006 起，他的工作主要專注在 web／後端／雲端服務上。寫程式、爬山、旅行、打電動曾是他一半的生活，在帶領團隊成為他 2023 的探索之後，2024-2025 回到與 AI 們競相寫 code 的戰場上，彼此常常不得不相讓。滑板或圍巾是他的隨身配備。假如圍巾沒出現的話，有人會問說今天 Keith 沒來喔？ ●●● Keith is a Lead Backend Engineer at iCHEF and served as Chairperson of PyCon APAC 2015. Since 2006, his work has mostly focused on web, backend, and cloud services. Coding, hiking, traveling, and video games once made up half of his life. After his 2023 team-leading quest, he returned in 2024–2025 to the battlefield of racing against AIs to write code—where both sides often have to give way. A skateboard or a scarf is an essential item in his daily gear. If the scarf isn’t around, someone might ask, “Is Keith absent today?”
