Learn Italian: È qui che lavora incredibilmente bene. - It is here that he works incredibly well.

When an Italian adjective ends in -le or -re (like incredibile, facile, or particolare), you must drop that final -e before adding the -mente suffix to form an adverb. That is why we get incredibilmente rather than "incredibilemente".

Why use the structure È qui che instead of just saying Lavora qui incredibilmente bene?

È qui che creates a cleft sentence, which is a structure used to put strong emphasis on one specific piece of information. Just like in English ("It is here that..."), it highlights the location as the crucial reason for his great work, rather than just stating a neutral fact.

Is bene following the same adverb rules as incredibilmente?

No, bene is an irregular adverb. While incredibilmente is systematically built by adding a suffix to an adjective, bene is simply the standalone adverb equivalent of the adjective buono (just like "well" relates to "good" in English). Because it modifies the verb lavora, you must use the adverb bene here.

The translation says "he works", but could lavora also mean "she works" here?
