About Me

Wern Jie Profile

Hello! I'm Wern.

19 y/o independent app developer

Wern Jie Lim or Lim Wern Jie 林文捷

With strong curiosity and a passion to learn more, I've picked up a wide range of interests - from math and science, to art and music, and most notably technology.

I love to look for ways to simplify my work, or make everyday tasks more enjoyable and easier to accomplish. Hence, when I stumbled across programming courses online in 2015, I was hooked!

Publishing these apps and more online has allowed me to learn a lot of details. Not only for programming, but also for customer support, UI and UX design conventions, user expectations, marketing strategies and more!

Over the years, I've also familiarised myself with many programming, scripting, styling and markup languages and technologies. I have a strong preference of using Unix and Linux environments as well. :)


That aside, I do have other things I love to spend my time on. For instance -


Distant Night
Autumn Breeze
It'll be okay

...and sometimes, I play the piano too!


All Is Found Piano Cover
Ode to Joy

I like editing videos as well! I've gained some experience with creating professional-style videos over the years, primarily in advertisement(-like) and fast-paced videos.
