He is a world expert on Web rendering, and an extremely capable C++ developer. One of their success recipes is to code up the various specifications directly, which is - today - the best way to go about this. They are also heavily test-driven.
He did not even use the C++ standard library, when he says "from scratch" it includes his own string class, for better or worse, which is fine since it's "just for fun", "to learn" etc.
And just when you think a library and an OS are crazy, he announced a browser and a JavaScript engine on top. Then a JIT compiler, then Jakt, their own novel programming language, because neither C++ nor Rust is what makes him perfectly happy.
More than his expertise I admire his modesty and kindness - unlike Linus etc. he is not full of himself, and each of his videos gives lots of credit name by name of who did what. A perfect role model for open source.
