Contractor installed this convoluted p-trap + elbow for the washer, and I'm not sure if it's up to code. Can you confirm and more importantly explain why or why not it's compliant?

UPDATE thanks all for the comments, just a few clarifications and updates:
all electrical work is work-in-progress, we're finishing it up tomorrow, it's still an active worksite. The old outlet and old bx wiring is being removed, we'll only have the newer wiring (and of course all outletd will be in their gangboxes and covers will be on)
the dryer vent will be changed and installed without sag when we finalize
the 4" abs drain connects to the old one with a rubber fernco gasket, those do require hose clamps and they're up to code (though the top clamp could be straightened!)
the water lines are pex, they're all good
we don't have a choice but to push the water up with the washer pump - the drain evacuates to the city sewer around hip level in that basement
The worries for me are really the 90° out of the sump pump and the other 90° into the drain column, shouldn't that be a downward Y? And the double S p-trap, is it creating some risk?
i'm assuming you're referring to the picture you posted in the comments? if so, kinda need a few clarifications. the 90 turning into the 4" and the connection they make? looks like a vent only from the way it's run, and i hope there isn't anything significant draining into that 4" from above. also what the hell is that 2"(?) line going up then back down?????
the s trap is a little fucky. definitely should've just been a regular p trap with a horizontally placed 45° and most of the code asks for a stand pipe to dump into or a wash basin and not direct connected like yours is to prevent unsavory situations.
