Peng-Yu Chen

Hi, I'm Peng-Yu Chen, originally from Taiwan.

I build apps for a living and for fun. By day I'm a Software Engineer in NYC; by night I'm shipping SaaS and apps, usually chasing whatever idea won't leave me alone.

I care a lot about craft — clean code, thoughtful conventions, and the little details that make software feel just right. It shows up in what I ship: apps that stay minimal and friendly, with nothing to figure out and nothing in your way. Try a few — they are all a click or a download away.

Most of my nights go to Zestimer, an interval timer for iPhone, Apple Watch, and the Home Screen. It is built for HIIT and stretching, and it talks you through every round so you never have to look down at your phone.

Drop in a YouTube link, a video, or a few images and it turns them into a workout you can follow. Lately I have been drawing cute animations into it, because a timer you enjoy looking at is a timer you keep coming back to.

Give it a try at zestimer.com — and tell me what you would change.

Wendy's Chicken is my first meal in the US.

C is the first programming language I learned.

I know a little Japanese, mostly picked up from anime.

My cat is named "Lola".
