Etymology: "Proficiently" is simply "proficient" with the suffix "-ly" added, and the suffix is far older than the adjective it sits on. The "-ly" ending descends from a Proto-Germanic word meaning "body" or "form," which in Old English became "-līce," used to turn an adjective into a description of how something is done. So the adverb is built from two parts with separate histories: a suffix that has been working this way for well over a thousand years, and a base word that arrived later. "Proficient" itself comes from Latin "proficiens," the present participle of "proficere," meaning "to make progress" or "to advance," built from "pro-" (forward) and "facere" (to do or make). The original sense was therefore about moving forward, and skill came from that idea of progress. Adding the suffix gives "proficiently," meaning in a way that shows advancement or competence.
