• Quant employment verification: CONFIRMED. Viktor Kozhuharov's LinkedIn (linkedin.com/in/viktor-kozhuharov, headline 'ICPC World Finals Gold Medalist | Oxford CS Grad') lists an actual full-time role as Quantitative Technologist at Radix Trading LLC (Chicago), 2024-present, plus a prior Quantitative Technologist Intern role there in 2023; these are employment/internship entries, not student programs or insight days. Identity is supported: the same profile links to the Oxford ICPC World Finals 2022 gold-medal team (cs.ox.ac.uk names 'Viktor Kozhuharov, Magdalen College, 3rd year CS'), and the Bulgarian IOI contestant of the same name (IOI 2019 bronze, 2021 silver) is recorded under Codeforces handle 'Sorting' on both stats.ioinformatics.org and cphof.org. Employer classification: Radix Trading LLC is a genuine quantitative trading firm, not merely a name containing 'quant' - Radix's own site describes it as 'a research firm, powered by technology and monetized through trading' and it is described as a Chicago proprietary/HFT firm. Caveat on provenance: the role evidence is the person's LinkedIn (self-reported / index-sourced), not an independent employer confirmation; the employer's quant-trading nature is confirmed by Radix's own primary site.2026
• The Radix internship (2023) converted to a full-time Quantitative Technologist role (2024), showing a two-stage entry at the same firm; both sit at a Chicago quant firm that also hires in London, so his Netherlands location implies Europe-side work.2024

• Competitive-programming record under handle 'Sorting': IOI 2019 bronze (Bulgaria) and IOI 2021 silver (Bulgaria); cphof lists $3,400 in contest prize money and links an AtCoder profile.2021
• Past internships: Software Engineer Intern at Lunchclub (2022, remote) contributing to Lighter DEX (an EVM-compatible, order-book DEX in Solidity), and Data Science Intern at Vela Partners (2021) applying Python ML to forecast startup success factors - two non-quant internships before the Radix roles.2022
• Bulgarian press documents the IOI identity: he is reported as a Ruse student (MG Baba Tonka) winning a 2019 IOI bronze, and Bulgarian delegations later list him among medalists - a separate national-media corroboration of the Olympiad name.2019
