Che Liu

Che Liu (劉澈) is a software engineer and competitive programmer from Taiwan who won a Silver medal for Taiwan at IOI 2022 (34th, rank 49). He studied Computer Engineering at The University of Hong Kong (2022-2024) and continued through the Cambridge-HKU joint dual degree into Information and Computer Engineering at the University of Cambridge, where he held a Cambridge Trust Scholarship. His industry experience is software-engineering internships at Qube Research & Technologies, a London-based global quantitative and systematic investment manager, alongside university research and teaching roles at HKU (XLANG NLP group, Software Security and System Lab). He is a co-author of the 2023 'OpenAgents' language-agents preprint and an ICPC World Finals competitor with multiple ICPC Asia regional golds.

• Quant employment verification: CONFIRMED. Che Liu has an actual software-engineering internship at Qube Research & Technologies (QRT) — the public LinkedIn profile (index/enrichment backbone, not an independent primary source) lists Software Engineering Intern roles at QRT in 2024 and 2025 and an intern headline 'Intern @ QRT'. Employment-lead identity is supported by an otherwise unique match on the IOI 2022 Taiwan silver medal and the '-tw' profile slug (IOI statistics page). QRT is classified as a quantitative firm from its own site ('global multi strategy investment manager') and its stated quantitative/systematic investment mandate; the role titles are software-engineering intern, not a titled quant-researcher/trader position. Index/enrichment-only attribution of the specific QRT stints to this individual remains the weak point and is labelled as such.Aug 15, 2022
• IOI statistics page confirms Che Liu represented Taiwan at the 34th International Olympiad in Informatics (IOI 2022), ranking 49th with 337.14 points and winning a Silver medal — an unambiguous competitive-programming identity anchor.Aug 15, 2022
• The QRT roles are recorded only as 'Software Engineering Intern' — there is no primary QRT announcement, team page, or publication naming him, so the specific internship dates and team are index/LinkedIn-only and should be treated as provisional until a QRT-hosted source is located.
• Taiwan's K-12 news and Taiwan News both name Liu Che (劉澈) among Taiwan's IOI 2022 medalists, an individual rank of 49th and a student of Taipei Municipal Jianguo High School, corroborating the Olympiad identity from a second, non-index family (national press).Aug 15, 2022
• QRT (Qube Research & Technologies) is a London-headquartered global quantitative and systematic investment manager operating across liquid asset classes, spun out of Credit Suisse in 2015 — this establishes the employer's quantitative-finance classification, so the QRT internship sits inside a genuine quant firm rather than a name that merely contains 'quant'.
• Codeforces handle 'cheissmart' is explicitly listed as Che Liu on Taiwan's IOI 2022 team in the public unofficial participant list, giving a verified competitive-programming handle loop (Codeforces -> IOI -> personal site -> GitHub).Aug 1, 2022
• GitHub account github.com/cheissmart is the subject's: it is the handle used on Codeforces (cheissmart) in the official IOI 2022 Taiwan roster discussion, the personal site cheissmart.github.io is his, and the profile carries the same competitive-programming identity.
• The profile's LinkedIn headline aggregates Cambridge, HKU, IOI Silver and ICPC World Finalist, and the same profile lists QRT, HKU research/TA roles and a Cambridge-HKU joint dual degree — a single, internally consistent self-description spanning study and internships; all of this is LinkedIn/index-derived and not independent primary-source confirmation.
• Educational path: entered The University of Hong Kong (BEng Computer Engineering, 2022-2024) and continued via a Cambridge-HKU joint dual degree into Information and Computer Engineering at the University of Cambridge, with a Cambridge Trust Scholarship in 2024 — source-level detail is LinkedIn/registry-derived.
