• Quant employment verification: CONFIRMED (with index-only caveat) - a Software Engineering Internship at Jane Street (London, 2025), a quantitative trading firm, is recorded, and the subject identity is strongly supported by Olympiad, Codeforces and LinkedIn records. The employment record itself rests solely on the profile index reproducing his LinkedIn and was not independently corroborated by a primary-source announcement; the Huawei roles are not quantitative finance.Jun 1, 2025
• Employer classification: Jane Street is a proprietary quantitative trading firm and market maker, so the 2025 Software Engineering Internship would be a quantitative-finance employer; Huawei is a telecom/consumer-electronics/technology firm and its 2023-2025 roles are not quantitative-finance roles.Jan 1, 2026
