• QUANT EMPLOYMENT VERIFICATION: CONFIRMED - Radix Trading LLC internship. Evidence: his LinkedIn profile (index/aggregator-derived) states a 'Quantitative Technology Intern' role at Radix Trading LLC, and theorg.com separately lists an Atanas Dimitrov under Radix Trading's Quantitative Analysis department. Employer classification: Radix Trading is a Chicago/New York/Amsterdam low-latency proprietary trading and research firm (radixtrading.co: 'a research firm, powered by technology and monetized through trading'), so it genuinely operates in quantitative/algorithmic trading - the role meets the quant-finance bar. Identity is supported independently: his IOI silver-2022/bronze-2023 Bulgarian record (IOI stats, CPHOF) and Oxford CS/Hertford enrollment (Oxford CS news) all cohere. Caveat retained: the role record itself rests on his own LinkedIn profile and an aggregator (theorg.com) rather than an independent company announcement or press - it is NOT independent primary-source confirmation. QuantCo (applied data-science/AI) and MYX AD (AI/digital-twin startup) are NOT quantitative-finance employers and their 'Software Engineer' entries do not count as quant roles.
• Index-only (LinkedIn-derived enrichment): profile states Quantitative Technology Intern at Radix Trading LLC; the same LinkedIn record lists past roles as Software Engineer at QuantCo and Software Engineer at MYX AD. This is index/aggregator-class evidence, not independent primary-source confirmation.
• Quant employment verification is complex and multi-employer: of the three leads, only Radix Trading is a confirmed quantitative/algorithmic trading firm; QuantCo is an applied AI/data-science company, and MYX is a Bulgarian AI/digital-twin software startup - neither operates in quantitative finance despite adjacent names.
• Radix Trading self-describes as 'a research firm, powered by technology and monetized through trading,' operating on major electronic markets across North America, Europe and Asia with machine-learning and statistical methodologies - i.e. a low-latency proprietary trading firm, confirming the employer operates in quantitative/algorithmic trading.2026
• Matriculated at the University of Oxford (Hertford College) to read Computer Science - named in an Oxford CS Department news piece (Oct 2023) as 'Atanas Dimitrov (Hertford, 1st year CS)' on one of three Oxford teams that took the UKIEPC 2023 top spots.Oct 23, 2023
• QuantCo self-describes as leveraging 'data science, engineering, and economics to help organizations turn data into decisions,' founded by four Harvard and Stanford PhDs; its products are algorithmic pricing, claims management and forecasting - a data-science/AI consultancy, not a quant fund or trading firm.2026
• Won a silver medal at IOI 2022 in Indonesia as an eleventh-grade student of the Sofia High School of Mathematics (team also won two silver and two bronze).Aug 15, 2022
• Aggregator-only: theorg.com lists an 'Atanas Dimitrov' within Radix Trading's Quantitative Analysis department ('7 people'), alongside a 'Quantitative Technologist Intern' - consistent with, but not independent confirmation of, the Radix internship; theorg pages are self-described unverified.
• Competitive-programming handle is 'aZvezda' on Codeforces, cross-linked to the IOI profile by the Competitive Programming Hall Of Fame; this is the strongest public alias link between the Olympiad identity and his other accounts.
• Radix Trading is a top-paying internship employer (~$200/hr, ~$34k/month per levels.fyi and reporting), and its intern roles sit on a 'Radix Trading University' job board (Quantitative Technologist C++ Intern, Quantitative Researcher) - confirming the Radix 'intern' title is a genuine internship program, not merely a student club or insight day.
• MYX AD (Sofia) is a technology company building 'MYX Analyzer', AI lease/site-document abstraction and digital twins for tower companies and operators - an AI software startup, not a trading or quantitative-finance firm.2026
• Won a bronze medal (relative rank 157) at IOI 2023, again representing Bulgaria.Sep 2023
