• Quant employment verification: CONFIRMED (see the dedicated note) - indexed Quantitative Technologist role at proprietary trading firm Radix Trading LLC (2022-2024, past) and indexed Jane Street software-engineer internships (2020, 2021); identity corroborated by official IOI profile, published Oxford address, GitHub and Oxford prize pages.
• Index lists Radix Trading as a PAST role (2022-2024) and describes him as 'previously' a Quantitative Technologist there, so no current employer is established and current employment is intentionally left unasserted.
• Radix Trading LLC (radixtrading.co) is a Chicago-HQ privately funded proprietary trading firm employing research-driven strategies on major electronic markets, with offices in New York and Amsterdam; this classifies his most recent indexed role as quantitative finance.
