4+ hours free course on ReactJS I created some 4-5 years ago. Even though the course is in Bulgarian (my native language), it can be viewed as a reference for my dev and mentoring skills along with the positive feedback from people in the comment section.
I also have video courses on JavaScript features and intro to GO programming language:
