[1] He also serves as the head coach for the PSP Gymers of the Women's Maharlika Pilipinas Basketball League (WMPBL).

Although he was named the top rookie, sharing the court with then UAAP MVP RR Garcia proved challenging for the younger guard, especially since he was relegated to the second option (something he wasn't used to).

Romeo's shooting percentage was somewhat below par at 32 percent, scoring a mere (for his standards) 9.9 points in his rookie season.

In his final year as half of FEU's dreaded backcourt duo, Romeo was expected to again lead the Tamaraws in scoring.

He also had the opportunity to play against Mark Caguioa in their first showdown against each other, scoring 27 points and leading a brave second-half comeback that almost denied Ginebra a 109–104 victory.

Before the start of the playoffs, however, Cabagnot was surprisingly traded for former Global Port player Sol Mercado from the San Miguel Beermen.

[11] The departure of Cabagnot proved beneficial to Romeo's rise to stardom, as he was able to blossom into the team's first scoring option.

His efforts weren't enough though, as the team struggled to get back into the win column in their remaining games after the all-star break.

The duo both led the team in scoring with 24.06 and 19.61 points, respectively,[16] while leading GlobalPort to its first ever Semi-Finals appearance against Alaska, only to lose the series.

In his first game with the Beermen, Romeo recorded 7 points and 4 assists in just 11 minutes of playing time but lost to the Columbian Dyip, 124–118.

[20] In Game 2 of the 2019 Commissioner's Cup Finals, Romeo came off the bench and scored 29 points and made 6 3-pointers in a 127-125 double overtime win.

[22] On November 25, 2024, Romeo was traded to the Terrafirma Dyip along with Vic Manuel for Andreas Cahilig and Juami Tiongson.

[2] As of the end of 2023–24 season[25][26] Playing for Manila West, Romeo was teamed up with Niño Canaleta, Rey Guevarra and Aldrech Ramos and Raphael De Vera, three pros with so much more experience than him.

The 6’0” Romeo was listed as among the season's top point producers going back to the qualifying legs of the 2014 FIBA 3x3 World Tour.

[29] The international basketball body named the GlobalPort scorer as the number one 3x3 player outside of Europe, Americas, and Qatar, and therefore earned his team a slot in the All-Star exhibition.

[33][34] Romeo was named to the Gilas Pilipinas 3.0 training pool in 2015, and joined the team for a pocket tournament in Estonia.

He also saw action in the 2015 William Jones Cup, where he emerged as the crowd darling, wowing Filipino and Taiwanese Fans alike with his crafty handles and scoring ability while posting a stat-line of 15.2 points in just 18 minutes of play per game in that tournament.

[35] Following his Jones Cup breakthrough, he was a member of the Gilas final lineup that competed in the 2015 FIBA Asia Championship, and had his best game against powerhouse Iran and India.
