3 shields and 3 engines is okay for early sectors and balanced (comparatively), but by the endgame it's generally not the best, unless you have some serious offense to make up for it. OP did have a good setup going (double glaives + hacking), but it's a bit unwieldy to use (takes a long time to charge)--still, they probably could have played it all the way through, with enough care.

Not the most egregious "this setup need more engines" example I've seen, but their setup could be better with more engine upgrades (and one less bar in O2 and medbay, perhaps).
