While competing on "Project Alpha," Lego was one of two contestants who remained Alpha for the show's entire run. Two months after his win and LYKN's formation, the group's single "(May I?)" premiered on May 5, 2023. In 2024, Lego got his start as a choreographer and assistant writer on LYKN's sixth single "Sugoi".

After making his acting debut in LYKN's short film "No Worries" in 2023, Lego booked his first TV role in the series "Thame-Po Heart That Skips a Beat".
