piriajr (Guilherme Barbosa) - Biography, settings, configs

Guilherme “piriajr” Barbosa is a Brazilian professional CS2 player. He is 23 years old and, as of early 2026, he plays for paiN on loan from Bounty Hunters.

He has been competing in the Brazilian scene since 2019, building experience across many rosters. His early teams included Santos, Falkol, Keyd Stars, DETONA, and Imperial, before he joined FURIA Academy in 2021 (with a short period on the bench during that time).

From 2022 onward, his career moved through several well-known local lineups: ARCTIC, then O PLANO (Aug 2022–Nov 2023), and adalYamigos (late 2023–early 2024). In 2024–2025 he rotated between Bounty Hunters and Fluxo, including brief bench periods, before returning to Bounty Hunters (Aug 2025–Jan 2026). In January 2026 he joined paiN on loan as part of the team’s roster plans for the 2026 season.
A good example of his impact: in a three-map series at Circuit X Retake São Paulo 2025, he posted 55 kills and a 1.30 rating, ending as the top performer in the match.

As a player, piriajr’s recent numbers show heavy focus on rifle damage and duel winning rather than AWP play. Over the past three months (56 maps), he held a 1.38 Rating 3.0, with elite “firepower” and strong “opening” impact, while his “sniping” score was very low—so he’s rarely the main sniper. For CS2 players watching his demos, the key lessons are how he takes rifle-first fights, converts opening advantages, and still stays useful in late rounds (solid clutch and trading indicators).
