What is your expertise on facebook/react?

[raisedadead]

I am a PhD student at UFMG, Brazil, working with techniques to assess the skills of developers by mining their activities on git repositories.

To calibrate my current approach, I need data about the skills of developers in a set of frameworks.

For example, I found that you have been contributing to GitHub projects that use facebook/react.

So, could please rank your expertise on facebook/react in a scale from 1 (novice) to 5 (expert)?

(important: I will use your answer exclusively in my research and only in aggregated and anonymised format).

Since 2015, I have been working with react based apps. However, I am still a learner if you please.
