It would be helpful if you could provide some examples of your work. "Complex" means something different to everybody, so your claim is hard to place in context.

"Less than a day" for "complex" web sites using nothing but raw JavaScript and hand rolled HTML & CSS does sound unusual, both in terms of the result as well as the workflow. Given the verbosity of JS DOM manipulation, I can't really envision a particularly good reason to go down that route for anything but the most performance pegged web applications.
