Notes2

• Quant employment verification: CONFIRMED. Si Young Oh (Siyoung Oh) worked as a Software Engineer Intern at DRW Trading Group in summer 2010 (May-Aug 2010). DRW Trading Group is a proprietary trading firm (principal trading / market-making), so this is a genuine role-in-quantitative-finance employer, distinct from student programs or competitions. Employer classification: proprietary trading firm (quant-adjacent trading). Evidence: the subject's own site siyoung.org states he 'interned in three different companies (Google, DRW Trading, Facebook)'; the LinkedIn-index enrichment lists 'Software Engineer Intern at DRW Trading Group'. The self-authored site corroborates the internship; the LinkedIn index supplies employer/role. Identity supported (same person: IOI 2007 Korea, CMU, Google/Quora/Snowflake).
