    I  joined JAO (previously CASC.EU) in 2008 as one of the first employees in the operations team. Appointed as Operations Manager in 2009 I have helped the company’s growth to its position of the single European Auction Office.

    Following the merger of CASC.EU and CAO and the creation of JAO SA in 2015, I have taken over the Business Development Manager responsibilities. On March 1, 2023, I took over the duties of the CEO.
