After speaking at Apple’s annual Worldwide Developers Conference, Bozoma Saint John lit up Twitter earlier this week.

Saint John, who currently serves as Apple Music’s Head of Global Consumer Marketing, got her start working with Pepsi and Spike Lee’s Advertising agency Spike DDB.

As it’s no secret that the tech industry is often lacking in diversity, Saint John’s appearance at the conference was welcomed enthusiastically both online and offline. During her presentation she unveiled the redesigned Apple Music. She also played a clip from Ghanaian artist Atom’s single “Yewo Krom” during her demo.

Saint John, who joined Apple in 2014, has always been outspoken about the issue of diversity in her industry, as one of few black women executives. She works closely with Adcolor, an organization that seeks to promote the work of people of color in the advertising industry. Saint John has been honored by Adcolor, in addition to being highlighted by Billboard, Fast Company, and Ebony magazines.

Saint John, who was born in Ghana, is also quite the server of looks, and frequently makes a splash on red carpets.
