Katarina Rampackova is a freelance dancer and choreographer. Born in Slovakia, she works and lives in Barcelona, teaching dance and working on a variety of artistic projects, including coaching disabled kids and co-founding a dance school in her home town of Kosice. She’s walking the Citi-sponsored bar area at Barcelona’s Mobile World Congress, oversized black jacket, walkie-talkie and a security badge that disguises her day job, but it’s indicative of the effect this global event has on the city. With more than 100,000 visitors from all over the world, the demand on resources is huge.
