Notes10

• Voloridge internship CONFIRMED by primary source: his own LinkedIn post (#VoloIntern #Summer2026) states he will join Voloridge Investment Management, LLC as a Quant Developer intern in summer 2026, matching the index lead for an 'Incoming Quant Developer Intern' from 2026-01.Mar 2026
• Quant employment verification: CONFIRMED. Identity: the LinkedIn profile linkedin.com/in/mesanu (headline 'CS @ Yale | IOI Medalist', Voloridge + Yale) is cross-linked to the same person as the IOI 2024 Moldova bronze medal record and the Codeforces 'mesanu' profile listing 'Mihai Esanu, Chisinau, Moldova / From Yale University'. Employment: a self-authored LinkedIn post by that profile (#VoloIntern #Summer2026) states he will join Voloridge Investment Management, LLC as a Quant Developer intern for summer 2026. Employer classification: Voloridge (Jupiter, FL) self-describes as 'a quantitative investment management firm' and advertises Quantitative Developer Intern roles on its careers page, so this is a genuine quantitative/systematic-investing role rather than a company that merely contains 'quant' in its name. Caveat: the post states a summer-2026 internship; the specific start month is not given in the primary source (the index-derived lead said 2026-01), and no salary/duration is published.Mar 2026
• Identity is corroborated by the IOI stats page and LinkedIn: the IOI contestant page for Mihai Esanu (Moldova, IOI 2024 bronze) and the LinkedIn profile linkedin.com/in/mesanu headline self-identify as 'CS @ Yale | IOI Medalist', tying the olympiad identity to the Yale CS student.Sep 6, 2024
• Employer classification: Voloridge Investment Management, LLC (Jupiter, FL) self-describes as 'a quantitative investment management firm' and its careers page advertises Quantitative Developer Intern roles, so the role is genuinely in quantitative/systematic investing, not merely a company whose name contains 'quant'.
• Represented Moldova at IOI 2024, earning a Bronze Medal with 218.81/600, world rank 175 (50.71% relative rank); the IOI page carries his contestant photo.Sep 6, 2024
• Index/LinkedIn-derived lead (not yet independently confirmed by a primary source): an 'Incoming Quant Developer Intern' role at Voloridge Investment Management, LLC starting 2026-01. Voloridge is a quantitative investment management firm (Jupiter, FL), so if verified this is a genuine quantitative-finance role; treat the role itself as an index-only claim until confirmed.
• Synthesis: his two paid/role entries outside olympiads are an undergraduate teaching-assistant post and a statistics-department research assistantship at Yale (per the index/LinkedIn), and the Voloridge Quant Developer internship for summer 2026; there is no evidence of any earlier or additional trading/market-making/hedge-fund employer or internship, so his quantitative-finance exposure is limited to the single Voloridge internship.
• Represented the Republic of Moldova at IMO 2024, earning an Honorable Mention (13 points, rank 400, 34.5%); the IMO record appears under the diacritic spelling 'Mihai Esanu'.Jul 20, 2024
• Accepted to Yale University on a full scholarship (announced April 2024 by his high school, Liceul Teoretic Orizont), and enrolled in a 2024-2028 Computer Science bachelor's.Apr 23, 2024
• Codeforces handle 'mesanu' is the same person: the profile lists 'Mihai Esanu, Chisinau, Moldova', states 'From Yale University', and carries a Candidate Master rating (current 1961, peak 2006), corroborating the olympiad and university identity.
• Synthesis: the identity resolves consistently across three independent source families - the olympiad record (IOI/IMO), a code platform (Codeforces listing the same name, city and Yale), and a professional profile (LinkedIn) - which is why the name-only namesakes (Romanian footballer, Moldovan wrestler) do not attach to this profile.
• Div. 4 problem-setter on Codeforces: mesanu authored problems/editorials for multiple Codeforces Div. 4 rounds (e.g. Round #849, #859, #886, #944, #928), consistent with the LinkedIn 'Problem-setter at Codeforces' role.
