Computer Science and Engineering undergraduate at Seoul National University and IOI 2018/2019 gold medalist for the Republic of Korea. Research-intern experience at DeepMetrics (AI healthcare) and KRAFTON (games); a crypto-quant internship at Hyperithm is claimed only in an index.

• Quant employment verification: UNRESOLVED. The only quant-adjacent employment lead is an index-only ClickHouse/LinkedIn claim of 'Intern' at Hyperithm, Seoul (2022). Hyperithm is verified as a quant/crypto asset manager - its own site states it delivers market-neutral returns through systematic arbitrage across digital and traditional asset markets and lists 'Proprietary Trading' as a field of business - so it qualifies as a quant employer, not merely a name containing 'quant'. But the role itself appears only in the ClickHouse people index; no independent primary source (Hyperithm team/intern page, a post, a resume) corroborates that Sebin Kim worked there. Identity is otherwise supported (IOI 2018/2019 for Korea, SNU CSE, matching LinkedIn). Because the sole quant role rests on index-only data lacking primary confirmation, treated as UNRESOLVED, not CONFIRMED.
• LinkedIn headline reads 'Undergraduate Student @ SNU CSE | IOI 2018', cross-linking the SNU CSE enrollment with the IOI 2018 Olympiad identity.
• Won gold medals for the Republic of Korea at the International Olympiad in Informatics in both 2018 and 2019 (rank 18 each year); the IOI statistics page is the primary source and links a Codeforces handle, while the Competitive Programming Hall of Fame is an aggregator of the same results.
• Competitive Programming Hall of Fame (aggregator) also records ICPC World Finals gold in 2021 (rank 4) and silver in 2022 (rank 6) and $5,400 total prize money - results consistent with competitive programming at Seoul National University, not primary-source confirmed here.
• Index-only claim (ClickHouse/LinkedIn): Research Intern at DeepMetrics in both 2023 and 2024. DeepMetrics is an AI-driven ICU-automation / digital-healthcare startup (Seoul), not a quant or trading firm, so these roles are ML research, not finance.
• Index-only claim (ClickHouse/LinkedIn): Republic of Korea Air Force military service as the current role from 2024 - the standard Korean military-service gap taken mid-university, which places active employment (if any) after service ends.
• Undergraduate in Computer Science and Engineering at Seoul National University (entered 2020) after Gyeonggi Science High School for the Gifted (2017-2020); depth of research-intern roles alongside a 7-year listed degree suggests a research-track CSE student.
• Handles 'blackbori' (Codeforces) and 'SebinKim' (AtCoder/Codeforces) are linked to this Sebin Kim by the IOI statistics page and the CP Hall of Fame aggregator.
• Index-only claim (ClickHouse/LinkedIn): Research Intern at KRAFTON Inc. (Seoul) in 2024. KRAFTON is a video-game developer/publisher (PUBG), not a quantitative finance employer.
• SNU competitive-programming strength: the same aggregator lists this name's ICPC World Finals medals (2021 gold, 2022 silver), implying sustained contest participation through university.
• No personal website, blog, GitHub, or published articles surfaced across web and profile searches; public footprint is limited to the LinkedIn profile, the IOI statistics page, and competitive-programming aggregators.
