Johnson Chen

Chief Technology Officer


Hello, I'm Johnson Chen. I'm currently working in the chief technology officer position at YAJAN-TECH.

My main skills are Android and Flutter, and the backend web API also has relevant experience. I've gained experience in project management and computer vision in recent years.

In 2017, I find myself interested in programming, not in hardware. So I left the Innolux company to join the Institute for Information Industry to learn to program and then start my programming life.


主要技能為Android應用層App開發及後端Web API開發,伺服器佈署也有相關經驗,近年有開始接觸一些影像處理相關經驗。
