She began her professional career in 2000, appearing in Waldemar Krzystek's television play Ballada o zabójcach.

She was awarded $20,000, and was offered a record deal with Universal Music Germany, which she rejected as she did not agree with its terms.

[citation needed] In 2009, Marina was cast as Amanda, the daughter of the main character (played by Tomasz Karolak), in the Polish television series 39 i pół.

[2][6] After parting ways with her manager Maja Sablewska in 2011, she began recording new material for her debut studio album.

[7] The album titled Hardbeat, which she released independently in November 2011, received positive reviews from music critics.

[11] In October 2013, while working on new music in a recording studio in London, Marina experienced singing difficulties which proved to be caused by a polyp on her left vocal cord.

As a result, she was forced to put her career on hold, and in May 2014 underwent laser microsurgery performed by Steven M. Zeitels to remove the polyp.

[13] That year, she also featured on James Arthur's song "Let Me Love the Lonely" from his second studio album Back from the Edge (2016).

The record debuted and peaked at number 50 in the Polish charts,[21] and was promoted with four singles: "News" with Kabe, "Nigdy więcej" with Young Igi, "Skandal (Odbijam)" with Smolasty and "Nie prowokuj".
