Career
Born in Florianópolis, Pottker graduated with Figueirense's youth setup. On 7 September 2011 he made his first team – and Série A – debut, coming on as a second-half substitute in a 1–1 away draw against Atlético Goianiense.

Pottker was subsequently loaned to Gandzasar, Ventforet Kofu, Red Bull Brasil and Linense, scoring five goals with the latter in 2015 Campeonato Paulista. On 16 May 2015, he was loaned to S.C. Braga in a season-long deal, with a buyout clause.

After only appearing for Braga's B-team in Segunda Liga, Pottker returned to Brazil and played for Linense, on loan, until the end of 2016 Campeonato Paulista. On 5 May 2016, after scoring seven goals, he signed a three-year contract with Ponte Preta.

Pottker finished the tournament with a career-best 14 goals (being also the top scorer among Fred and Diego Souza), being a key unit as his side finished eighth; highlights included a brace in a 3–0 away win over Santa Cruz on 30 June 2016. He also topped the charts in the 2017 Campeonato Paulista with nine goals, as Ponte finished second.

On 16 February 2017, Pottker was sold to Internacional, but remained at Ponte until the end of the year's Paulistão.

On 18 July 2017, he made his debut for Internacional, against Luverdense, scoring the only goal of the game in the 93rd minute.
