MrJuneJune

+ + + +

Hi, my name is Juntae, but most people call me June or MrJuneJune.

+ +

I am a software engineer with experience spanning a wide range of companies, from small startups to FAANGs....

+

I know it is lame to work for them, but I have a dog so I need to put foods on my table.

+ +
+ +
+ +

During my free time, I like to write codes mostly in C, Python, and Typescript. All in mono repo styles using mercurial and bazel. (I know that is mentally ill...)

+

Feel free to check it out. My bad code..
