StelluR broke out on to the scene at the start of the Halo 5 season winning many 2v2 and 1v1 tournaments. His first big opportunity came when he joined OpTic Gaming on December 7th, 2015. After four online qualifiers with no placings higher than top 16, He left OpTic to join Leftovers. Leftovers qualified for the NA Regional Finals and were shortly after picked up by the Renegades organization. Renegades' first event, which also happened to be StelluR's first major event, was the X Games Aspen 2016 invitational, where they finished 4th. They then competed at the Halo World Championship NA Regional Finals 2016, where they finished top 8, good enough to qualify for Halo World Championship 2016. At Worlds, Renegades finished top 8, narrowly losing to Team Allegiance in a reverse sweep.
After Worlds, StelluR and Spartan parted ways with Renegades, opting to join Team Liquid alongside APG and Eco. The team first attempted to qualify for the Summer Pro League at the Summer Qualifier, but were unable to place in the upper half of their group. After replacing the injured APG with Assault, Liquid qualified for the League by finishing 1st in the Last Chance Qualifier. Liquid had a rocky start to the season, not winning a single match until Week 4, after dropping Assault for Danoxide. The new roster ended up finishing 2-12, good enough for only 7th place. At Relegation, Liquid were able to keep their spot by finishing 1st.
Despite their qualification, StelluR left Liquid to join Enigma6 Group alongside Cratos, bubu dubu and Suspectorduring the offseason. E6 won their first tournament together - 2050 Chattanooga. Shortly after this event, StelluR made a post on the Team Beyond forums claiming that he had been dropped from E6, citing salary concerns among other issues. The organization confirmed the release of StelluR later that day. StelluR remained on E6's active roster until Week 4, when he left to join Evil Geniuses alongside Lunchbox, Roy, and Ninja. EG attended UGC St. Louis 2016with StelluR on board, placing 3rd. Returning to the Pro League season, the new roster lost six straight matches, only managing to win their last two on Week 7, finishing with a 5-9 record just good enough to take 6th place and avoid Relegation. In the final match of the season, StelluR helped EG defeat Team Liquid, which resulted in his former team Enigma6 being sent to Relegation. At ME Las Vegas, EG finished top 6 after wins over Most Wanted and Enigma6 and 3-2 losses to Team EnVyUs and Str8 Rippin.
During the offseason, StelluR left Evil Geniuses, eventually returning to Team Liquid alongside Rayne, Penguin and Eco. The new roster's first event was UGC St. Louis 2017, where they proved they were a team competing for 1st place as they nearly defeated OpTic Gaming in the Winners Finals before taking out #1 seeded Team EnVyUsin the Losers Finals and again losing a very close series to OpTic in the Grand Finals. At ME Las Vegas 2017, Liquid qualified for Halo World Championship 2017 after sweeping Pnda Gaming, and solidified themselves as the #2 team in North America with two dominant victories over Team EnVyUs. They lost to OpTic Gaming 4-1 in the Finals and went home in 2nd place. At Worlds, Liquid were placed in a pool with Luminosity Gaming and London Conspiracy, both of whom they 3-0d to earn a top seed in the bracket. In Winners Round 1, they again defeated Team EnVyUs, this time 4-3. This was followed by a 4-0 sweep over Str8 Rippin and a 4-1 WB Finals loss to OpTic Gaming. In the LB Finals, they were unable to overcome a hot Team EnVyUs, who defeated them 4-2 to end their night with a 3rd place finish.
At the first event on 2017 settings, UMG Daytona, Liquid faced Splyce a whopping four times over the course of the weekend - twice in pool play, of which each team won one, once in Winners Bracket Round 2, which Liquid won, and following a 5-game loss to OpTic Gaming, once more in the Losers Semifinals which was won by Liquid in a seven-game affair. They then moved on to face Team EnVyUs, looking to reclaim their spot in the top 2 after losing it at Worlds. EnVy had other plans however, sweeping Liquid in the best-of-7 and sending them home in 3rd.
