Early in his career, Lekavičius Justynas played for various Lithuanian mix teams but struggled to find success. He began competing professionally after signing with MAD Lions at the end of 2021. Despite the promising start, the team’s performance fell short of expectations, leading to its disbandment. Nevertheless, Lekavičius continued competing, and soon after, he claimed gold at REPUBLEAGUE Season 3.
In August 2022, jL signed with the Norwegian organization Apeks. His debut major concluded with a 3rd-4th place finish. In June 2023, Lekavičius received an offer from NaVi, which he eagerly accepted, joining their roster. With NaVi, jL achieved significant milestones in his career, earning a silver medal at ESL Pro League Season 18 and securing gold at the PGL CS2 Major Copenhagen 2024 and the Esports World Cup 2024.
