Xmithie first entered the League of Legends in January 2011, quickly hitting level 30 and jumping into ranked duo queue, playing with his now ex-girlfriend. For a time during Season 1, Xmithie got stuck and hovered around the 1700 ELO range. However, once he began play solo in ranked, he sprang up to 2200 ELO, where he met other 2000 ELO players to form a team called Soldier Front. Team Soldier Front competed in small tournaments, eventually meeting APictureOfAGoose during a Go4LoL cup in October 2011. After playing against Team Soldier Front, A PictureOfAGoose invited Xmithie to join as their AD Carry substitute player, a position which he accepted.

Continuing their success in online tournaments, Xmithie took first place on July 6, 2012, at the National ESL Pro Series Season 3 with his team mTw.NA. During the three-month-long online group stage, mTw.NA placed third, going 4-3 winning 9 games out of 16 by defeating 4Nothing 2-0, Epik Gamer 2-0, Counter Logic Gaming Prime 2-0, and Team Legion 2-0, while falling to Team Dignitas 1-2, Curse Gaming 0-2, and Team SoloMid 0-2. As Team SoloMid was forced to forfeit, mTw moved on up to the grand finals. There, Xmithie carried on the momentum and defeated Team Dignitas 2-0, taking home first place with his team mTw.NA.

In May 2017, before start of the Summer Split of Season 7, Xmithie transferred from CLG to Immortals. He attended the Season 7 World Championships with Immortals, but the team did not continue past the Group Stage.

Following the announcement that Immortals would not be included in the franchising of the NALCS, Team Liquid announced that Xmithie would be a starter on the team in the 2018 Spring Split on November 22, 2017 along with other Immortals members Olleh and Pobelter . They would become the spring split champions, defeating 100 Thieves 3-0, with Xmithie providing a crucial play in Game 1 by stealing the Baron Nashor from 100 Thieves to help turn the tide in Team Liquid’s favor.
