• Quant employment verification: CONFIRMED for role existence, index-level only. Evidence: (1) the subject's own LinkedIn headline self-describes 'Ex-intern@Jump' and the LinkedIn enrichment index lists job titles 'Quantitative Trading Intern at Jump Trading Group' and 'Quantitative Researcher at GIC'; (2) RocketReach, an aggregator, independently lists 'Quantitative Trading Intern @ Jump Trading LLC'. Identity is well supported by primary sources (IOI 2019 official statistics: gold medal, Singapore; cphof: ICPC 2025 World Finals rank 50 with University of Cambridge; teammate Erekle Roinishvili's post naming Eu-Shaun Leong on the Cambridge ICPC team). Employer classification: Jump Trading Group (jumptrading.com) is a proprietary quantitative trading/market-making firm, and GIC is Singapore's sovereign wealth fund running quantitative investment research - both genuinely operate in quantitative finance. Caveats: no independent primary source (e.g. a Jump careers/team page) was found; the roles are stated at index/self-reported level, NOT independently primary-source confirmed, and the hinted dates (Jump Jun-Aug 2025; GIC Jan-Jun 2023) are unverified. Internships are actual work roles, not competitions, insight days, camps, or offers; no blanket 'incoming offer' claim is made.
