• Quant employment verification: CONFIRMED. Identity is supported by primary olympiad records (IMO 2019/2020/2021, IOI 2020/2021), the Cambridge Part II dissertation, and a Slovak media feature, all matching name, school and location. An actual role is listed: Quantitative Technologist at Radix Trading LLC (current, from Sept 2025) on his LinkedIn profile (retrieved via the people index, an index-only/self-reported claim, not independently confirmed by the employer). Radix Trading LLC is verified as a genuine proprietary quantitative trading firm (Chicago, ex-DRW founders, systematic futures/equities/crypto). A prior Software Engineer Internship at QuantCo (2024) is at a data-science/ML firm, not a trading firm; two unnamed 'Stealth HFT firm' roles (Quantitative Researcher 2023, Algorithm Developer 2021-2022) remain unverified.
