Marianna started her career in 2002, becoming one of the first authors of a gambling news site - the predecessor of Casinoz. Even before the heyday of the online industry, she covered its formation: from the first European licences to underground clubs with pirated slots.

In 2009, when the project was transformed into Casinoz, Marianne became the portal's key reporter. In 20+ years in the profession, she has seen the evolution of gambling: from underground rooms to legalisation in the US, from Flash slots to blockchain casinos. Her materials are a chronicle of the industry, a nexus of eras where every event is explained through historical context.
