Hi!
I am a JavaScript developer with an advanced experience in Angular, React, React Native, JQuery. Being honest with you, I do not have an experience in Underscore.js. But to make a good argument, I have an experience in teaching Programming and I have my own YouTube Channel where I post educational videos about programming. I would be happy to hear more details about the job (e.g. how many videos, targeted audience, etc..)
Thank you!
Hatem
