David 'frozen' Čerňanský began his career as a professional esports player in 2015, joining the nEophyte team. With the team, he won the Mistrovství ČR 2015 tournament, after which he moved to eXtatus at the beginning of 2016, where he also won gold at Mistrovství ČR 2016. Additionally, in the new team, David won at Headshot Cup #4, Mother Russia 1xBet, and Mistrovství ČR 2017 (Czech Championship 2017). However, in July 2018, the team was disbanded, and Čerňanský worked with lesser-known mixes, where he didn't achieve notable success.
Despite this, in early 2019, the esports player caught the attention of NoChance and signed a contract with them, returning to the winning path. In this lineup, the player won gold medals at Pixel.bet Brawl: Nordic vs. Europe and LOOT.BET Hotshot Series Season 1. In March, Davin moved to mousesports, where he won dozens of tournaments. Among the most significant victories, we should highlight gold at Europe Minor Championship - Berlin 2019, DreamHack Masters Malmö 2019: European Qualifier, and Flashpoint Season 3.
From October 2021 to December 2023, David played for MOUZ. He helped the team secure 1-2 place at Intel Extreme Masters XVI - Winter: European Qualifier and Intel Extreme Masters XVII - Dallas: European Open Qualifier #1, and he also won gold at Thunderpick World Championship 2023: European Series #1 and ESL Pro League Season 18.
At the end of 2023, David 'frozen' Čerňanský signed a contract with FaZe Clan, where he currently plays. He helped the team secure silver at Intel Extreme Masters Katowice 2024, PGL Major Copenhagen 2024, and Perfect World Shanghai Major 2024, as well as winning gold at Intel Extreme Masters Chengdu 2024.
