• Quant employment verification: CONFIRMED. Shreyan Ray's identity is supported across primary sources: IOI 2023 India silver medal (stats.ioinformatics.org/people/8057), Codeforces handle Dominater069 as India's first Legendary Grandmaster (IIT KGP alumni news), and B.Sc. Mathematics and Computing at IIT Kharagpur (Codeforces profile). His LinkedIn profile (surfaced via the people index) lists an actual role "Quantitative Trading Intern, Jane Street" (Hong Kong SAR), start 2026-05, no end date, and a matching headline. Jane Street is a genuine quantitative trading firm / market maker (janestreet.com), so the employer classifies as quantitative finance. An IIT Kharagpur 2025-26 internship placement list (scribd.com/document/894399394) independently names Shreyan Ray at Jane Street. Caveats retained: the role evidence is LinkedIn-derived (people index) plus an uploaded placement-list document, NOT a Jane Street primary page or a first-person statement; the 2026-05 start with no end date may represent a completed summer internship or an incoming offer rather than a currently-active role, so the exact status is uncertain. No other quant-finance role or internship at any bank, asset manager, or energy/crypto trading firm was found.2026
