• Quant employment verification: NOT CONFIRMED. Identity is supported (LinkedIn, IOI 2024 record, Codeforces 'Sedmoklasnikut', TU Delft enrolment all cross-corroborate). However, the trading-firm records (IMC Trading Launchpad, Jane Street FTTP, Discover Citadel & Citadel Securities, Optiver Trading Academy) are student/insight programs rather than employment or internships, and the only role-like entry, Problem Setter at Musala Soft (2021), is at a software-services firm, not a quantitative-finance employer. No verified past or present quantitative-finance role, internship, or offer is documented in public sources.
• Public record shows only student/insight programs at trading firms (Optiver Trading Academy 2025; Discover Citadel & Citadel Securities 2026; Jane Street FTTP 2026; IMC Trading Launchpad 2026). These are educational/recruiting programs, not employment or internships, and do not by themselves establish a quantitative-finance role.
