Hi! I'm Yukai Huang

Hi, my name is Yukai, which means "happiness" in Japanese(It's a Chinese name though).

I'm a developer who loves to build projects around productivity or just for fun.

The following list contains the projects I built in recent years. I will update them occasionally.

Some earlier projects can be found on my GitHub. I track WIP projects and ideas with this GitHub Project Board publicly. I also write userscript for browser sometimes, I'll put them on Gist.

You can also find me on Twitch. I do live coding sessions sometimes.

Projects I created

    • A TypeScript project with deno runtime. Test the AI capability to implement the easiest type of OCR.
    • Also provide a GreaseMonkey UserScript that can pre-fill captcha for you.
