Jiandido was 2 for 15 with a run for Aruba in the 2010 Pan American Games Qualification Tournament, fielding .893 as a 2B/LF.  He was signed by Philadelphia Phillies scout Jesús Méndez in 2011.  He split 2012 between the GCL Phillies (.205/.283/.398 in 29 G) and Williamsport Crosscutters (.208/.245/.271 in 13 G), fielding .985 between the three outfield spots. In 2013, he was with Williamsport (.299/.353/.430 in 33 G) and the Lakewood BlueClaws (6 for 44, 2B, 2 3B, 2 BB).
At age 20, he played for the same two teams, batting .266/.325/.498 with 14 homers and 16 steals (in 21 tries) for Williamsport and .224/.287/.329 in 27 games for Lakewood. Among Phillies farmhands, he tied Brian Pointer for 5th in dingers (15) and tied Enmanuel Garcia and Tyler Henson for 6th in swipes (19). He tied Rowan Wick for the New York-Penn League lead in home runs, was second with 129 total bases (five behind Hunter Lockwood) and was third in slugging (between Chris Breen and Terrell Joyce).
Tromp spent all of 2015 with Lakewood, slipping to .216/.268/.354. His six triples tied Roman Quinn and Rhys Hoskins for third in the Phils chain. He split 2016 between the Clearwater Threshers (.240/.290/.456 in 59 G) and Lakewood (.274/.335/.506 in 65 G), bopping 20 homers, with 33 doubles, 5 triples, 70 runs and 14 steals in 18 tries. Among Phillies minor leaguers, he tied Josh Tobias for 6th in runs, tied Nick Williams for 3rd in doubles, tied for 3rd in triples, tied Darin Ruf for 5th in home runs, was 7th in RBI (between Tobias and Jorge Alfaro), tied for 10th in steals and was 3rd with 221 total bases (after Dylan Cozens and Hoskins).
He continued his upward climb in 2017, producing at a .285/.329/.485 clip with 31 doubles and 18 home runs for the Reading Fightin Phils and going 2 for 9 with a double and a walk for the AAA Lehigh Valley IronPigs. He handled 194 chances error-free in the outfield. He was second in the Eastern League in two-baggers (3 behind Richard Urena), 4th in total bases (221, between Aderlin Rodriguez and DJ Stewart), 4th in extra-base hits, 7th in hits (130, between Carlos Tocci and Matt Oberste) and 8th in slugging (between Francisco Mejia and Stewart). On the Phillies farm, he was 7th in runs, 2nd in doubles (11 shy of Andrew Pullin), 8th in home runs (between Pullin and Jan Hernandez), 7th in RBI and 5th in total bases (between Hoskins and Wilson Garcia).
The Aruban flyhawk started the winter of 2017-2018 with the Navegantes del Magallanes, going 5 for 27 with a double and five walks, and finished it in Puerto Rico with the Indios de Mayagüez (.151/.233/.283 in 16 G). His struggles continued into 2018, when he only had 13 doubles, 4 homers and 4 steals between Reading (.225/.312/.329 in 89 G) and Lehigh Valley (3 for 15, 2B, BB) in a major drop-off from the prior year. That ended his time in the Phillies chain.
Tromp hit .264/.349/.399 for the independent Ottawa Champions in 2019 and .219/.242/.313 for the Tiburones de La Guaira in 2019-2020. He began 2021 well with the ASD San Marino club (.469/.591/.750 in 8 G)  then played for the Netherlands in the Final Olympic Qualifier (his brother Chadwick had played for the team a few times already). He was not the only member of the 2010 Aruban team to make the 2021 Dutch squad; Sicnarf Loopstok was also on both teams.
In his Netherlands national team debut, he batted leadoff and started in right field against Venezuela. He struck out in the first against Jhonathan Díaz but singled in the third off Eduardo Paredes. In the 6th, he got the first Dutch run, singling off Danny Rondón and coming around on a Juremi Profar fly later in the inning. He singled against Freddy Pacheco in the 8th to make it a three-hit day, but the Netherlands lost.
