Quality of a product is determined by 3 things: Material, Expertise and Will.
The best of Material is useless without an Experienced worker and Experienced workers is useless without Will.
In the computer world Material like Node.js, C++, etc is freely available so needless to say the quality is heavily depends on Expertise and Will.
Will is how much a person want something, the fact of the matter is that you will always get a better, more innovative and friendly experience if your hiring someone whom isn't in it just for cash.
Experience is the type of thing that you can't read about to become good at, you have to shed blood to get it (or in the computer world: sacrifice a keyboard).
