Marcelo "nyezin" Ramos entered the Counter-Strike scene in 2021. His professional career began with the little-known team MUITA MIRA POUCA MIDIA, where he was unable to secure any titles. After that, the esports player also had unsuccessful stints with 10org and Kadett Rebaixado.
In May 2022, he received an offer from Liberty and accepted it, signing a full contract with the organization. Marcelo played for the team until November 2022 and managed to win his first trophies during that time. He was a silver medalist at Gamers Club Liga Série A Relegation: September 2022 and Gamers Club Liga Série B: September 2022, won bronze at CBCS Elite League 2022 Season 1: Open Qualifier #4, and placed 1st-2nd at CBCS Elite League 2022 Season 2: Open Qualifier #1. He also finished 1st-4th at CCT Season 1 South America Series #2: Closed Qualifier and CBCS Elite League 2022 Season 2: Closed Qualifier.
His strong performances caught the attention of paiN Gaming Academy, which he joined in January 2023. With the team, he secured gold at Gamers Club Liga Série A Relegation: January 2023, Gamers Club Liga Série A: January 2023, FACEIT Cash Cup: South America - Winter 2023 #9, Game Arena Cup 2023, Gamers Club Liga Série A: February 2024, and Global Esports Tour Rio de Janeiro 2024. He also earned silver at FiReLEAGUE Academy 2023, Gamers Club Liga Série B: September 2023, and FACEIT Cash Cup: South America - Autumn 2023 #12.
However, despite his successes, Marcelo never received a promotion to the main roster, which he had been hoping for. As a result, he decided to leave the team and joined Case Esports in May 2024. Here, he won the EPL World Series: Americas Season 8 title, earned silver at Dust2 Brasil Liga Season 3, and secured bronze at ESL Challenger League Season 47 Relegation: South America, United21 South America Season 2, and Circuito Estadual FERJEE 2024. Additionally, he placed 1st-2nd at Ace South American Masters Fall 2024: Open Qualifier #2 and Perfect World Shanghai Major 2024: South American Qualifier.
In February 2025, Marcelo "nyezin" Ramos switched teams again, joining RED Canids. With them, he placed 1st-4th at Ace South American Masters Spring 2025: Closed Qualifier. After that, he went inactive and remains without a team at the moment.
