• Quant employment verification: CONFIRMED. Two internships and a current-analyst registration support quant employment. Identity anchor: IMO 2018-2020 Serbia contestant (imo-official.org) shares name, City University of Hong Kong education and Singapore location with the LinkedIn profile listing Jump Trading QR/QT and the Jane Street/Jump Trading internships. Employer classification: both employers are genuine quantitative trading firms - Jane Street's own site describes it as 'a quantitative trading firm and liquidity provider', and Jump Trading is a proprietary trading firm (principal/market-making across traditional and crypto markets). The registered representative record at JUMP TRADING, LLC (advisorcheck, CRD# 8296401, started 2026, passed Series 57TO and SIE) is a US FINRA registration matching the name and employer, but is index-only (advisorcheck aggregates FINRA/regulatory filings) and is not independent primary-source confirmation.
