To OP - I think the resume is a clever format, and riding a language's popularity is a great way of putting yourself out there, especially as a junior.
To others, the "Traits" section -- how much impact does this really matter to the hiring managers? You're hired for what you know, but you're fired for who you are. Is it worth it to expand on these "traits", or is it a fluff area that can be replaced with something more meaningful?
For hiring software devs, I don't care about soft skills on a CV. If I'm concerned, I'll pull that thread in an interview. I'd much rather see those traits demonstrated rather than claim you have them and fall short of my expectations.
Recently, I've also seen people put progress bars for soft skills on a CV, as if they're close to mastering the skill or at least levelling up. It normally takes up a lot of space and is virtually meaningless.
Was once hiring for a IT Support role and someone applied with a star-based system for their skills. I still to this day do not know what 4.5 Stars in "Cables" could ever possibly mean.
For soft skills, saying "can do X" isn't useful. The only written example that I'd even consider is you demonstrating X as part of a written sample (STAR answer), or BQ during an interview.
