These employment entries are currently index/LinkedIn-derived and have not been independently confirmed by a primary source.

• Quant employment verification: UNRESOLVED. The roles (Tudor Group Portfolio Manager Global Macro from 2020; Rokos Capital Management Assistant Portfolio Manager 2018-05 to 2019-10; Goldman Sachs Credit Flow Quant 2014-07 to 2016-01, plus Crude Oil Derivatives Trader 2016-2018) are currently derived only from the LinkedIn/index profile record and caller-supplied leads, not from an independent primary source such as a company page or a dated filing. Employer classification: all three are genuine quantitative-finance firms - The Tudor Group (Tudor Investment Corporation) is a global macro hedge fund; Rokos Capital Management is a London macro hedge fund; Goldman Sachs is a bank whose credit/oil derivatives desks are quant-heavy - so each employer names a real quant-finance operation, but that confirms the employer, not this person's employment, dates, or role. Identity is supported by the IMO record (Serbia, 2007-2010) matching the profile, but no accessible source independently corroborates the employment entries. Verify against a primary source (company, filing, or press) before treating as confirmed.
• Silver medals at IMO 2008 and 2009 both scored 29 and 27 points with full marks on problems 1,2,4, indicating early strength in algebra/number theory relative to geometry (P3/P6 scores low).Jul 2010
• Competed at IMO for Serbia in four consecutive years 2007-2010, an unbroken run that is itself evidence of sustained top-tier competitive standing in the Serbian olympiad team.Jul 2010
• An X/Twitter account '@bobaduki' is titled 'Dusan Milijancevic', matching the name but carrying no cross-link to the LinkedIn/Goldman/Rokos profile; treat the handle as name-matched only, not identity-confirmed.
