Homebrew PCBs

Will the pizza even get warm in this thing? Most of it is outside most
of the time! Seems terribly inefficient.
It does say "From freezer to perfect in minutes." so maybe this is not
designed to actually bake a real pizza, just warm a frozen ready-made
one.

The wedge shape could be a problem for SMD. It would be easier to dial
in a linear heated zone.
Generating IR is not a problem, just buy some of the old style
infrared heaters like this:

Some of the small ovens actually use this kind of quartz tube, others
use metal tubed heaters.
