As a member of OG, he has played in three iterations of The International, winning in 2018 and 2019, and has also won two Major championships tournaments.

Pham began his professional Dota 2 career by joining Invictus Gaming in March 2016 as a substitute for Ferrari_430.

[11] Despite a bad start at The International 2018's group stage, OG finished fourth and were seeded into the upper bracket of the main event.

Considered underdogs during their entire time at the event, OG and Pham advanced to the grand finals and won the tournament by defeating PSG.LGD in the best-of-five series 3–2.

[18] The commentators noted that Pham developed a completely novel carry Io strategy, which was previously considered to not be viable, which he utilised to great effect.

[23][24] However one year after his retirement, in 2022, he returned to the pro scene playing as a substitute player for Team Liquid and Royal Never Give Up in Riyadh Masters and PGL Arlington Major.

[26][27] Prior to the International 2018, Pham transitioned to playing as a carry, leaving the solo mid position to Topias "Topson" Taavitsainen.

[30][31] Pham is noted for his long breaks from professional play, something that is generally recommended against, as the competitive landscape of Dota 2 can change quite rapidly.
