expert + -ise (French abstract-noun ending) = 'the quality of being an expert,' i.e. the tried-and-tested knowledge an expert owns. It's the abstract mass noun for what an expert has.
Usage Guide
Note the pronunciation: expertise ends in /-iːz/ ("-eez"), with the stress on the last syllable — ek-spər-TEEZ — unlike expert (EK-spert). It is uncountable: say 'a lot of expertise,' not 'an expertise' or 'expertises.'
