Finding someone who has strong experience of WYSIWYG editor

Hi, everyone.
I am looking for a developer with strong experience and deep knowledge about ProseMirror.
https://prosemirror.net/

I inform once again!
I am really serious and need an only real experienced developer!
Please Read This Detail Carefully: only a person who is very familiar with ProseMirror.
If you don't know prosemirror well, do not bid, do not waste my time.

Here is an advanced editor based on ProseMirror :
https://github.com/chanzuckerberg/czi-prosemirror

You can also check its live demo:

I need to make an editor like czi-prosemirror but add several additional functionalities.

First of all, you must have a test so that you can prove yourself.
The test is not complicated.
The czi-prosemirror is a react project and you have to convert it to same editor with html, css, plain javascript, jquery - without any framework such as React, Vue, etc.
Or you can make a same one from prosemirror basic.
Of course. I will pay for your test. But timeline is 3 days.

Only bid if you agree with all of the above requirements.

Please put "I can do it without doubt!" on top of your proposal so that I can know you read all of this project details.

Looking forward to meet a real expert.
Thank you.
