I did not know if this person until today, very glad for their monetary success.
However, the technological choices that he makes seem fine for the type of web applications he's building: seemingly simple, one-off projects to which he adds more features as needed.
I don't know if that approach would work on maintaining a large code base in the case of a meatier project that needs to be maintained for the long term. My own experience doing web dev (which is not my specialty) is that HTML,CSS,JS quickly become unmaintainable when you try to scale them without a well though out architecture and some prior experience.
