Kallista is currently studying at Minneapolis College of Art and Design as a senior, where she is working to earn her degree in Bachelor of Fine Arts in Graphic Design. Besides her pursuit in her degree, she is actively practicing design further as an intern at Next Creative Agency. Thus far, she had worked with a diverse group of clients—such as Bintang Sempurna Printing and Versailes Furniture—to create logo design, digital advertisements, packaging designs and an array of print design. Proving her strong performance to the agency, she has been given the opportunity to be one of their representatives for Asia HP Digital Print Excellence Awards 2021, where she is currently creating a book while experimenting with a vast selection of print materials and techniques: laser cutting, UV coating, OVG ink, metallic ink. In the past, she had experiences creating digital advertisements for Casio, Tri Network and RedDoorz Hotel during her time interning at an e-commerce giant: Lazada Indonesia.

Aside from designing, Kallista enjoys immersing herself in novels and studying history. Ever so often, she may also be found doing water sports or dreaming about her next trip.
