• Quant employment verification: UNRESOLVED. The lead that Oleksii Masalitin is a 'Junior Quant Researcher at Atto Trading' (start Sep 2025) originates only from his LinkedIn profile as retrieved through an enrichment index and from the aggregator theorg.com; neither is independent primary-source confirmation of the role. His identity is well supported (same-name LinkedIn tied to the IMO 2020 Ukraine contestant, Kyiv-based, university mathematics student). Atto Trading itself is independently classified as a quantitative trading firm by its own careers site ('a quantitative trading firm focused on developing data-driven strategies to trade global financial markets'), so the EMPLOYER's quant classification is confirmed even while the individual's current role remains index/aggregator-only and could not be matched to any Atto team page, company post, or press item naming him. Treat the role as an unverified lead pending a primary source.Sep 17, 2026
• Won a silver medal for Ukraine at IMO 2020, placing 86th with 28 points (P1 7, P2 7, P3 0, P4 7, P5 7, P6 0); the official IMO team page confirms the olympiad identity that anchors this profile.Sep 22, 2020
• Atto Trading's own job board states the firm is 'a quantitative trading firm focused on developing data-driven strategies to trade global financial markets' and lists 'Junior Quant Researcher (Data Scientist)' among its Kyiv roles, so both the employer's quant classification and the role title in his lead are real, recurring at the firm.Sep 17, 2026
• Index-listed past roles on his LinkedIn are R&D Engineer at Huawei, Content Creator (math learning platform) at Summatic, and Teacher at Kvanta STEM; no dates or primary confirmations were found, so these are unverified labels rather than a confirmed timeline. None of the three is a bank, fund, or trading firm, so they add no quant-finance employment.Sep 17, 2026
• LinkedIn (via enrichment index) lists a Bachelor's degree in Mathematics at Taras Shevchenko National University of Kyiv (2021-2025) and prior schooling at Novopecherska School (2019-2020), placing him as a Kyiv-based mathematics student through 2025.Jan 1, 2025
• An ORCID record (0009-0008-4621-9362) named 'Oleksii Masalitin' lists a 2023 ScienceRise food/bioengineering article with unrelated co-authors (Tytarenko, Krychkovska) and no personal information; the subject is unrelated to mathematics and is likely a namesake, so it is NOT attributed to this profile.Sep 30, 2023
• Kvanta (kvanta.xyz) is a Ukrainian olympiad-math education organization whose 'achievements' page appears alongside RMM 2020 results in search; his Kvanta STEM 'Teacher' listing is consistent with an olympiad-math background but is an index-only label, and education/coaching work is not quantitative-finance employment.Jan 1, 2023
• A search hit places 'Oleksii Masalitin' in the Romanian Master of Mathematics 2020 results set; RMM is a companion elite olympiad to the IMO, consistent with his IMO 2020 Ukraine selection, but his name was not confirmed on the RMM participant page read, so this is low-confidence corroboration only.Feb 1, 2020
