Farhan closed off his final year in the junior circuit by captaining Indonesia's mixed teams in the Asian and the World Junior Championships.

He brought home a bronze medal from the Asian Junior Championships and became Indonesia's first ever boy's singles world champion.
In September, Farhan won his first senior title at the Indonesia International tournament in Medan. In the next tour, he lost at the first round of Indonesia Masters Super 100 I to Aidil Sholeh.
2024 was Farhan's first full year at the World Tour.

He went on to his Sudirman Cup debut as the team's second-ranked men's singles player, making his mark with a victory against world number 3 Anders Antonsen at the group stage and coming home with a bronze medal.
After strings of early exits against more experienced players, Farhan secured his first World Tour title at the Macau Open Super 300.

At the Korea Open, he overturned a losing situation to Weng Hongyang to reach the semi-finals, where he conceded to eventual champion Jonatan Christie. Unfortunately, he did not manage to join his compatriots at the Australia Open finals, after suffering a reverse sweep in a quarter-final match against Chou Tien-chen.
Farhan wrapped up an eventful year with a second SEA Games team event gold and winning the individual men's singles title against compatriot Zaki Ubaidillah.
Farhan's Super 1000 debut at the Malaysia Open ended early due to stomach problems plaguing his match against Alex Lanier. He rebounded at the Indonesia Masters, snatching Indonesia's sole title at home with a 25-minute victory against Panitchaphon Teeraratsakul. However, he missed out on a consecutive final opportunity after losing at the Thailand Masters semi-final to eventual champion Zaki Ubaidillah.
