After working as a model, Fronckowiak did amateur theater and began her television career by appearing in commercials. In 2010, she made a cameo appearance in a scene in the Brazilian soap opera
Viver a Vida. In 2010, she signed with Rede Record, and the following year she joined the cast of
Rebelde, where she played the character of Carla. On the show, Carla is a member of the pop band
Rebeldes. The group went on to hold performances outside the program, with Fronckowiak as one of its six members. In October 2011, the former model was voted Girl of the Year in Meus Prêmios Nick, a teen event sponsored by
Nickelodeon Brazil. In 2012, she won two categories in the Troféu Internet, and was nominated to Troféu Imprensa, one of the biggest annual awards on Brazilian television. In May 2013, Fronckowiak published the book
Inclassíficavel: Memórias da Estrada (Unclassifiable: Memories of the Road). According to her, a major publisher turned down the manuscript for "being difficult to classify". This experience influenced the naming of the book. The book includes poetic reflections and a collection of short stories that recorded during the Rebeldes tour of forty cities throughout Brazil. Since 2014, Fronckowiak has worked as a television presenter. She signed with
Rede Bandeirantes to work on the show
A Liga. In February 2015, she was hired by
Globosat to present
Destino Certo, which premiered on 3 September 2015. This was her first solo program, and it was renewed for a second year. In 2015, Fronckowiak was invited to join the cast of
El Hipnotizador, the first bilingual
HBO television series in Brazil. It was broadcast simultaneously in all Latin American countries by
HBO Brasil and
HBO Latin America Group, and also on Hispanic channels in the United States. That same year, Fronckowiak launched a fashion blog called
Sweet Ray of Style and received the support of major brands, such as
Chanel. In 2016,
Netflix announced Fronckowiak as part of the main cast of
3%, the first Brazilian original series on the streaming service. ==Selected filmography==
