It may be worth asking yourself if your career goal is to be "The React Guy". If that is your desire, you are on-track. But I've found that most people I know who hit an absolute wall in their career are folks who tie their career identity to a specific technology. Because over the course of multiple decades, odds are your chosen tech will fade.

If I were you, I'd put this energy into learning something new, and your video content can show your progress and show off your ability to pick up new skills.

I must disagree with your comment, I don't think re-creating React ( without looking at the source code ) makes you the React guy, the skills to be a good React developer, and the skills to be a developer that can create a framework like React I believe are not the same.

I think by creating a React-like framework what I will showcase is a deep understanding of the inner workings of the browser ( for optimization), the inner workings of React, and a good knowledge of languages and tools used to create this framework.
