About Me


Hi, I'm Peng-Yu Chen and I grew up in a small island called Penghu in Taiwan. Now, I'm a Software Engineer at Google NYC. Before that, I was pursuing my M.S. in Computer Science at NYU.
I received my B.S. in Computer Science from National Taiwan University and developed my enthusiasm for software engineering during that time.
Being fascinated by remarkable software practices and engineering excellence, I always believe in following good coding conventions.
