• Quant employment verification: CONFIRMED. Two independent source families support an actual software-engineering internship at Optiver: (1) the person-index enrichment record (index-only) lists 'Software Engineer Intern, Optiver, Amsterdam, North Holland, Netherlands, 2026-' as a current role, and the same index-based people_search returns the matching title/company; (2) the caller-supplied employment lead (unverified) independently listed two 'Optiver Software Engineer Intern' entries. Employer classification is corroborated by primary pages: Optiver's own About page ('Global market making and trading') and its Wikipedia article ('proprietary trading firm and market maker for various exchange-listed financial instruments') establish Optiver as a quantitative market-making / proprietary trading firm. Identity is supported: the LinkedIn slug matches the name, the IOI-stats profile confirms IOI 2021 Bronze / 2022 Silver for Kazakhstan, and the GitHub profile (@LastZhabka, name 'Sakhmoldin Mukhammadarif', Hong Kong) links back to the IOI stats page. Caveat: the Optiver internship appears in the person index/LinkedIn-derived record and the caller lead, not yet in a quarter-independent primary Optiver announcement, so the role is CONFIRMED as a role while its exact dates remain index-sourced.2026
• Optiver is a global market maker and proprietary trading firm (technology- and research-driven), headquartered in Amsterdam, per its own About page and Wikipedia: 'proprietary trading firm and market maker for various exchange-listed financial instruments' - so it qualifies as a quantitative trading/market-making employer rather than merely a name containing 'quant'.2026
• Synthesis: all three documented roles at the point of the index snapshot (Optiver software engineering; Huawei AI research; HKUST Visual Intelligence Lab research) place him on an AI-systems and trading-technology path; only the Optiver role is in quantitative trading - the two Huawei and HKUST roles are artificial-intelligence research, not quant finance.2026
• Research internships at Huawei Hong Kong Research Center (HKRC) in 2024 and 2025: multiscene video generation with spatio-temporal diffusion transformer architecture (2024) and multimodal LLM distributed inference / vLLM encoder-cache work (2025). These are AI-research roles, not quantitative-finance roles.2025
• IOI record confirmed by the official IOI statistics site: 2022 contestant for Kazakhstan, Silver Medal; the CPHOF profile shows IOI 2021 Bronze (rank 140) and IOI 2022 Silver (rank 87, 257.94/600).2022
• Index-only claim: the person-search index lists the Optiver Software Engineer Intern role in Amsterdam as current from 2026 and is derived from LinkedIn-type profile data, not an independent employer announcement; treat the current-employment timing (2026-) as index-sourced and subject to confirmation.2026
• HKUST ICPC team member: with Taimas Korganbayev and Raiymbek Baishuak (team HKUST1), placed 46th / Silver Medal at the Nanjing Regional Contest on 9 Nov 2025, evidence of continued high-level competitive programming during university.Nov 9, 2025
• Education: Bachelor's degree in Data Science + Artificial Intelligence at The Hong Kong University of Science and Technology (2023-2027); earlier High School Diploma from Nazarbayev Intellectual Schools, Kazakhstan (2017-2023).2027
• GitHub handle @LastZhabka (display name 'Sakhmoldin Mukhammadarif'), located in Hong Kong and linking to the IOI stats profile - a self-cross-link that corroborates identity between the developer account and the olympiad record.2026
• Undergraduate Research Assistant at the Visual Intelligence Lab @ HKUST (2025), researching knowledge-distillation methods for Multimodal Large Language Models.2025
• Competitive Programming Coach at Nazarbayev Intellectual Schools (Almaty, Kazakhstan), 2023-2024: taught advanced algorithms and data structures and prepared students for olympiads - a teaching role taken while still a Kazakhstani high-school/university student.2024
• National Olympiad in Informatics (Kazakhstan) gold medals 2020-2023 are reported in profile/roster material, consistent with his Kazakhstan representation and his 2023-2024 role coaching olympiad students at Nazarbayev Intellectual Schools.2023
