Born in Amsterdam, Ondaan played in the youth academies from HFC Haarlem, AFC Ajax and AZ Alkmaar. In 2011, he had to leave Ajax and he was signed by AZ. He never played a professional match for AZ.
Telstar
In the summer of 2013 he moved to SC Telstar, where he signed an amateur contract. He only played three matches in which he scored four times for Telstar, before he was signed by Willem II.
Willem II
Willem II sold winger Virgil Misidjan to PFC Ludogorets Razgrad and wanted Ondaan to replace him. Because Ondaan had an amateur contract with Telstar, Willem II was able to sign Ondaan without any transfer fee. He transferred to his new club only two months after signing for Telstar. He made his debut for Willem II on 23 August 2013 against Sparta Rotterdam (3–0 win). His in June 2016 expiring contract was not extended.[2]
