Puppey started his first steps into the DotA 2 competitive scene with Natus Vincere among players such as Dendi and Artstyle, as they competed in The International 2011. They went undefeated throughout the whole tournament, winning the then-big $1,000,000 USD grand prize. They also won the Electronic Sports World Cup 2011 and took home $12,000 USD. In both of these tournaments, he demonstrated fantastic prediction with the hero Chen’s ability to send his teammates back to base. Puppey became Natus Vincere’s Captain after ArtStyle’s departure from the team in October 2011.

After winning the Dota 2 Champions League Season 2 in 2014, things began to go south for Puppey, getting a 7-8th place at The International 2014, Puppey suddenly left Natus Vincere with Kuroky. The community started saying rumors about why he would leave a team he stayed with for four years.

Puppey and Team Secret won Shanghai Major 2016 in March 2015 after beating Team Liquid in the finals.

On 16 February 2016, former team manager Evany Chang accused Team Secret of not paying prize winnings to her and former players. On 9 October 2016, former player EternaLEnVy wrote a blog post detailing several instances of the organisation, in particular team director Kemal and Puppey, failing to pay players on time, lying about payments and sponsorships, and taking a 10% cut out of prize winnings without informing the players. Later that day, another former player, MiSeRy, released a blog raising similar issues, and claiming Secret did not pay him until he asked several times. He also backed EternaLEnVy’s claim that Puppey was the only player aware of the organization taking a 10% cut.
