Nurbakyt Madibek

Nurbakyt Madibek (aka 'Nur', handle jmadibekov / MadNick) is a Kazakhstan-based software engineer currently at Nethermind, an Ethereum execution-client and L2 research firm, in Almaty. He is a three-time International Olympiad in Informatics medalist for Kazakhstan (Silver 2016, Silver 2017, Bronze 2018) and a competitive programmer on Codeforces (MadNick). After school he accumulated software-engineering internships in London: ChocoFamily (Almaty, 2021), Meta (2022), Bloomberg LP (2022-2023), and Citadel (2023) — the latter a hedge fund/market maker — before joining Nethermind, where his public GitHub work targets Taiko/Ethereum L2 infrastructure.

• Quant employment verification: CONFIRMED. Two finance-adjacent engineering internships are documented on the LinkedIn profile whose identity cross-checks (name, Almaty, Nethermind headline and the jmadibekov handle match the GitHub account carrying the IOI/ICPC record). (1) Software Engineer Intern, Citadel (London, 2023) — Citadel is a multi-strategy hedge fund and market maker, squarely a quantitative-finance employer; the role title is Software Engineer, so it is a software role at a quant firm, not a quant-research/trading role. (2) Software Engineer Intern, Bloomberg LP (London, 2022-2023), building an end-to-end trades dashboard on the Bloomberg Terminal — Bloomberg LP is a financial-data/market-infrastructure company, finance-sector but not a hedge fund. Caveat: both are stated only in the enriched LinkedIn/index record (index-only), not yet corroborated by an independent primary page; the 2023 Citadel entry should be treated as strong but single-source. Nethermind (current) and Meta (2022) internships are not quant-finance.2023
• Current Software Engineer at Nethermind (Ethereum execution-client/L2 R&D firm), confirmed by both the GitHub org membership (NethermindEth) and the site domain nethermind.io; recent public repos are Taiko/Nethermind Surge L2 work (alethia-reth Rust client, raiko). Nethermind is blockchain infrastructure, not a quantitative-finance employer.2026
• Current role Software Engineer at Nethermind (nethermind.io), an Ethereum execution-client/R&D company, dated 2025- in the enriched profile; Nethermind is blockchain research/software, not a quant-finance firm, so it does not satisfy the quant-employer criterion.2025
• Citadel Software Engineer Intern (London, 2023) is listed on the LinkedIn profile matched to this identity; this is index/LinkedIn-derived and not independently corroborated by a primary source. Citadel is a hedge fund/market maker, so the role is quant-finance-adjacent though titled Software Engineer, not a quant research/trading role.2023
• Won IOI medals in three consecutive years representing Kazakhstan: Silver 2016 (411 pts, 29th overall), Silver 2017 (278.04 pts, 58th), Bronze 2018 (262 pts, 93rd). A sustained top-tier high-school competitive-programming record, not a single result.Sep 8, 2018
• Software Engineer Intern at Bloomberg LP (London, 2022-2023) — built an end-to-end trades dashboard on the Bloomberg Terminal; finance-software role, listed on the enriched LinkedIn profile (index-only).2022
• GitHub bio: 'a software dev with a competitive-programming background: 3 IOI medals and an ICPC regional medal' — his own framing ties the olympiad record to a software-engineering, not research/trading, trajectory.2026
• Software Engineer Intern at Meta (London, 2022), working on Meta Business Suite Creator Marketplace data pipelines and APIs; index-only LinkedIn claim.2022
• Competitive-programming surface spans IOI, TopCoder/Codeforces (handle MadNick, ~2203 current / 2350 max, international master), Yandex.Algorithm 2017, and IPSC 2016 (team KTL#1); he published olympiad archives repos (github olympiadarchives, 2019-2021), indicating a long-running contributor to the regional CP community.2019
• Represented Kazakhstan in the ICPC semifinal (NWERC-area) with teammates Nazarbek Altybay and Orazbek Khibadullin (team 'SAU BOLWI', ~2022) — a university competitive-programming team, distinct from the high-school IOI teams.Apr 2022
• Earlier Software Engineer role at ChocoFamily (Almaty, 2021), building a notification feature for a delivery-driver hiring platform; index-only LinkedIn claim.2021
• Early personal repos (2021) 'umailer' (Python email service) and olympiad-archive websites place his independent building activity in 2019-2021, before the London internships — evidence of a self-directed developer rather than a purely coursework profile.2021
