• Quant employment verification: CONFIRMED. Alexandru Milu (IMO 2011 Romanian team; Duke BS Math/CS 2016) worked as an Options Trader at Susquehanna International Group, LLP (SIG) from Aug 2016 to Sep 2018 - a genuine past full-time role, not a student program, insight day, camp, or incoming offer. Employer classification: SIG is a global quantitative market-making and proprietary trading firm (options market maker), i.e. real quantitative-finance activity. Evidence: his own LinkedIn role history and headline ('former options trader at SIG'), corroborated independently by his GitHub profile (github.com/alexandrumilu), which self-describes 'Former SIG options trader. BS in Math/CS from Duke. Silver Medalist at the IMO.' The LinkedIn role entry and GitHub bio are two separate self-published surfaces; the LinkedIn role is index-enriched (index-only for structured dates). No primary SIG page naming him was found, so the role rests on his self-published profiles rather than a third-party confirmation. Since 2019 he has been a Software Engineer at Google, so the trading role is historical.Aug 2016
• Since 2019 he has been a Software Engineer at Google in New York; his LinkedIn shows the role as current, so any claim that he is still a trader would be stale.2019
• He worked as an Options Trader at Susquehanna International Group (SIG), the global quantitative market-making and proprietary trading firm, from 2016 to 2018, per his own profile headline and role history; SIG operates in quantitative trading/market making, so the role is a genuine quant-finance position rather than a student program.2016
• He graduated from Duke University with a BS in Mathematics/Computer Science in 2016 (listed in Duke's 2016 commencement program).May 2016
• Alexandru Andrei Milu represented Romania at the 2011 International Mathematical Olympiad, scoring 25 points (problems 7-0-4-7-7-0) for a Silver medal at rank 66.Jul 2011
• His GitHub profile (alexandrumilu) self-describes as 'Former SIG options trader. BS in Math/CS from Duke. Silver Medalist at the IMO. San Francisco, California' - an independently published identity corroboration of the LinkedIn profile's SIG/Duke/IMO claims.
• Duke Today's 2016 student-laurels list states 'Alexandru Milu received the Karl Menger Award for Superior Performance in the Putnam Competition', and the Duke Math department's Karl Menger Award page lists him among past recipients.May 2016
• In the 2015 Putnam Competition (Dec 2015) Duke's team of Feng Gui, Alexandru Milu and Tony Qiao earned Honorable Mention; he is not listed among the 2015 Putnam Fellows on the official results page.Dec 5, 2015
• At Duke he was a lecturer (2014-2015) for a half-credit course preparing students for the William Lowell Putnam Competition - consistent with his own Putnam record and the Menger Award.2014
• He was named to Romania's team A for the 2011 Balkan Mathematical Olympiad (BMO), alongside Tudor Padurariu, Octav Dragoi, Radu Bumbacea, Viorel Andrei Bud and Omer Cerrahoglu.2011
• He was a PRUV Fellow at Duke (2014), conducting undergraduate research in knot theory.2014
• Location conflict: his LinkedIn lists New York, New York while his GitHub profile lists San Francisco, California; the two self-reported locations differ, so any single 'current location' should be treated as approximate.
