Raúl Alejandro Ocasio Ruiz was born on January 10, 1993, in San Juan, Puerto Rico and was raised in Canóvanas and Carolina.

[4] For many years, Alejandro and his father lived in the mainland United States, mainly Miami and New York City, where he got inspiration from the R&B and dancehall genres.

[10][11][8] After quitting soccer, he was left in a light depression, so, to improve his mood, he decided to switch to a music career and begin publishing songs through SoundCloud in 2014.

Alejandro was then featured in multiple collaborations, including Kevin Roldán and Khea's "Pa' Tu Casa"[15] and "Luz Apagá" with Ozuna, Lunay and Lyanno, that year.

A subsequent remix of "Toda", featuring Argentine artist Cazzu and fellow Puerto Ricans Lenny Tavárez and Lyanno, was released in May 2018.

[22] In July 2021, Alejandro was featured on the Jennifer Lopez song "Cambia el paso" ("change the beat") and appeared in its accompanying music video, shot in Miami.

[23] In April 2022, Alejandro featured on Colombian artist Shakira's single "Te Felicito" and in its accompanying music video.

The song proved to be among his most successful, reaching the #1 position (or within the top-five) across Latin America and Spain (#2), as well as charting in some non-Spanish speaking countries, including Brazil (#10), Croatia, France, Portugal, Switzerland and Ukraine.

[25] It includes collaboration with artists such as Laura Pausini, Romeo Santos, and Bad Bunny, blending elements such as salsa, reggaeton and other genres.

[27] He has cited Chris Brown, Michael Jackson, Ricky Martin, Daddy Yankee, Elvis Presley, Bruno Mars and Ciara as a few of his musical inspirations.
