• Quant employment verification: CONFIRMED - Daniil Smelskyi's own LinkedIn profile lists him as Quantitative Developer at Ansatz Capital (Greater London), dated 2025-present, and his profile headline reads 'IOI medalist, ACM ICPC finalist, Quantitative Developer at Ansatz Capital'. Ansatz Capital is classified as quantitative finance: its own site states it 'is a quantitative trading firm based in New York', and trade press reports its 2025 expansion into London. Caveat: the role evidence is the subject's self-reported LinkedIn profile as returned by an enrichment index; no employer-side primary source (Ansatz team/careers page naming him, or a press mention) was found to independently corroborate the role. Identity is supported by the IOI 2018 official record (Ukraine, gold) and the matching Codeforces handle. Student programs are not the basis for this CONFIRMED status - it rests on an actual named professional role.Aug 2025
• Represented Ukraine at the International Olympiad in Informatics 2018 and won a gold medal; the IOI statistics page lists him as a 2018 Ukraine contestant with a linked Codeforces profile danya.smelskiy.2018
• Employer classification check: Ansatz Capital operates genuine quantitative trading, not merely a 'quant'-named company - its homepage describes it as a quantitative trading firm based in New York and names its team as scientists and engineers.
• Career timeline (self-reported on LinkedIn): Quantitative Developer, Ansatz Capital, Greater London, 2025-present; Embedded Software Development Engineer II, Amazon, Amsterdam, 2024-2025; Software Engineer, SQUAD, Kyiv, 2021-2024; Software Engineer, Ring Ukraine, Kyiv, 2020-2021; Problem Setter and Tester, CodeChef, 2018-2019. The last three and the Amazon role are non-quant; Ring and SQUAD are Ukrainian software/engineering employers, not trading firms.
• Trade press (efinancialcareers, 2025-03-26; Hedgeweek, 2025-03-27) reports Ansatz Capital, described as an 'elusive quant trading firm', is expanding into London - context for why a London-based Quantitative Developer role appeared in 2025.Mar 26, 2025
