Профессиональное резюме разработчика

Можете не мучатся. Материал бесполезен. Он не пройдет АТСку. Никто такие резюме не читает)

Посоветуй пожалуйста дельный курс/видео/статью/шаблон для резюме на американский рынок

After you get the link, on the top right there's two squares for a button that says duplicate, that'a how you access it and make it your own :).

This is nothing but an online portfolio which after a while will have many duplicates of so I wouldn't use it as it is. Also there's a general rule to not to rate your skills but he includes that in the webiste. Don't use this to apply for jobs

I wouldn't trust this too much he's an engineer not a recruiter. Go to this subreddit and read the wiki https://www.reddit.com/r/EngineeringResumes/

How do we access the template?

It is not clear how to use this. I opened the course archive, and it has a link to notion, but it doesn't seem that I am able to save or edit it. And the badges.json file is just random characters.

You can open the badges.json file with Figma.

we have no idea too, but this is all the author give after payment.

I see. But I figured it out thanks to @Dandy comment above.

how to open it?
