Where to go next as a web developer?

Question

Career in IT

Soft skills, I have good ones.
Normally I can talk with the customer.
English somewhere at the level, B1. Once I taught, and even forced my relatives to speak to me only in English: D But then I realized that I needed more practice, and in my muhosransk. This makes no sense.
Java Script I know is by no means perfect. But we try, with the familiar Java Script developers to collectively solve problems on code wars (in the evenings), we also make reports on various features and new technologies there.
Also, I know a lot about the v8 environment and JIT where Java Script is executed and turned into bytecode.
Relatively normal knowledge of pure SI. Does it make sense to delve into it? And learn how to work with the network, and data at a lower level?
In fact, I want more knowledge on computer sience. But I do not want to do in the table. That is, will I be more valuable as a hard worker. If I understand everything at a lower level? Or is it better to write a database in javascript that will work in the browser, but after that I will start clicking the Olympiad problems.
