Notes6

• Identity confirmed: IOI statistics profile ([contact omitted]), Codeforces handle Na2a, GitHub github.com/na2a, and LinkedIn (uk.linkedin.com/in/nazarbek, headline 'Quant Dev') all name Nazarbek Altybay and share the competitive-programming thread, tying the Olympiad identity to the professional one.
• Quant employment verification: CONFIRMED. Work history includes an actual role as Quantitative Developer at Portofino Technologies (2024-2025) and Quantitative Technologist at Qube Research & Technologies (2025-), plus a 2019 Software Development internship at Jane Street; identity is supported by IOI/Codeforces/GitHub/LinkedIn agreement. Employer classification is primary-source confirmed: Qube Research & Technologies is a British quant hedge fund (Wikipedia: 'quantitative investment firm', hedge funds, ~US$38bn AUM Mar 2025); Portofino Technologies self-describes as 'Digital Assets Market Making' and is independently reported as a crypto market maker. Caveat: the individual role entries rest on the LinkedIn index (index-only), not HR/primary confirmation, and no non-index source independently verified the role dates.
• Won Silver at IOI 2016 (Kazakhstan, 328 pts, rank 74/308) and Silver at IOI 2015 (Kazakhstan, 402.55 pts, rank 41/322).Aug 1, 2016
• Career ladder from the index (all index-only): Yandex Software Engineering Intern (web crawler team, 2018, Moscow, C++/Python) -> Jane Street Software Development Intern (2019, London, OCaml/internal projects) -> Leap Tools Software Developer (Toronto, 2021 and 2023-2024, Python) -> Meta Software Engineering Intern (2022, London) -> Portofino Technologies Quantitative Developer (2024-2025) -> Qube Research & Technologies Quantitative Technologist (2025-). The 2018-2019 internships precede the 2020 UNIST degree, consistent with a student-internship timeline.
• Qube Research & Technologies is a systematic/quantitative hedge fund (predecessor Credit Suisse Quantitative and Systematic Asset Management, founded 2016, ~1,400 employees, ~US$38bn AUM 2025) - it unambiguously operates in quantitative finance.
• Portofino Technologies operates in crypto market making (site tagline 'Digital Assets Market Making'; CoinDesk reports it as a crypto market maker founded by ex-Citadel Securities staff), satisfying the crypto-trading-firm criterion.
• Codeforces handle Na2a and TopCoder handle nazarbek are the competitive-programming identities the IOI statistics page itself links, both connecting to github.com/na2a and the LinkedIn profile.
• Education (index-only): Bachelor's degree in Computer Science, Ulsan National Institute of Science and Technology (UNIST), 2016-2020; high school Kazakh-Turkish lyceum for gifted students (2011-2016); languages English, Russian, Kazakh.
• No non-index primary source (press, personal site, résumé, interview, or conference page) was found that independently names the QRT or Portofino roles, so those entries remain index-only rather than independently corroborated employment.
• Current base is London, United Kingdom, per the current role location and the UK LinkedIn subdomain (index-only).
