- Quant employment verification: CONFIRMED. The subject's LinkedIn profile (slug elshadimo) lists a current role as Software Engineer at Citadel, New York, described as 'Fixed Income Macro', from 2024. Citadel is a large multi-strategy hedge fund and market maker, i.e. a firm that operates in quantitative trading, so this is an actual employment role rather than a student program, insight day, camp, scholarship, or incoming offer. Identity is supported by the profile's University of Waterloo Computer Science 2011-2015 record and Azerbaijani/Turkish languages, consistent with the Azerbaijan IMO contestant of 2010/2011. Caveat: the role is self-reported from LinkedIn profile data and was not independently corroborated by a separate primary source.May 2024
