Jirayus Jinapong

Jirayus Jinapong is a Thai mathematics student and olympiad competitor. He won a gold medal for Thailand at the 2019 International Mathematical Olympiad (35/42, rank 18) and previously competed in Thailand's olympiad selection; he was also a high scorer in the UKMT British Mathematical Olympiad. He attended Kamnoetvidya Science Academy (KVIS) in Thailand and, as of a 2025-dated profile, is a third-year mathematics undergraduate at Trinity College, University of Cambridge. He works publicly as a mathematics tutor (MAT/STEP/olympiad) and authors olympiad training problem sets. A LinkedIn/people-index record lists a 2023 summer role of 'Quantitative Research & Trading' at Quantedge, a Singapore-based quantitative hedge fund; this role appears only in index/aggregator data and is not confirmed by a primary source.

• Quant employment verification: UNRESOLVED. The Quantedge role (Quantitative Research & Trading, 2023-06 to 2023-08) appears only in the LinkedIn/people-index record; no primary source (Quantedge page, his own post, or resume) confirms it. Employer classification is CONFIRMED: Quantedge is a Singapore-headquartered quantitative investment-management hedge fund (founded 2006), so the company genuinely operates in quantitative finance. Identity is supported by IMO 2019 gold, Trinity College Cambridge, KVIS, and BMO records. Because the role rests on an index/aggregator alone, the role itself is not independently confirmed, and student programs/offers would not qualify.Sep 17, 2026
• Won gold for Thailand at IMO 2019 with 35/42 (rank 18, 97.3%), including full marks on problems 1,2,4,5,6 — one of Thailand's three golds that year.Jul 2019
• Identity is corroborated across four independent source families (IMO official results, Superprof tutor page naming Trinity College Cambridge, LinkedIn, and KVIS school), which pins the olympiad identity to the Cambridge mathematics student rather than a namesake.Sep 17, 2026
• Third-year mathematics undergraduate at Trinity College, University of Cambridge (as of the 2025-dated tutor profile), placing his university start around 2022-2023; LinkedIn lists a BA in progress.May 2025
• Appears in UKMT British Mathematical Olympiad high-scorer lists: scored 60 in the 2019 BMO Round 1 list and 38 in BMO Round 2, matching his self-description as a British Maths Olympiad winner in Rounds 1 and 2.Dec 2019
• His public footprint is concentrated on competition mathematics across every source family — tutoring, problem-set authoring, olympiad results — with no public code, talks, press interviews, or personal website found, so the index-derived Quantedge entry is the only finance data point and it stands alone.Sep 17, 2026
• Authors and self-publishes olympiad training materials on Scribd (Evaluation Tests for IMO Students, Summer Homework for IMO Students dated September 2025 and for TMO Students dated February 2026), so his most recent dated public artifacts are competition-coaching problem sets rather than professional or research output.Sep 2025
• Works publicly as a mathematics tutor: Superprof listing at 100 GBP/hr, rated 5.0 from 4 reviews, teaching MAT, STEP and olympiad material, with a public work email ([contact omitted]) posted in a LinkedIn comment.May 2025
• Attended Kamnoetvidya Science Academy (KVIS), Thailand's elite science high school, and represented it in a competition — establishing the high-school identity behind the olympiad results.Jan 2018
• LinkedIn summary states he is 'interested in pursuing a career in the financial section [sector]', which frames the index Quantedge record as consistent with a stated finance interest but is not evidence that any specific role occurred.Jan 2024
• Listed among high scorers of the UKMT British Mathematical Olympiad Round 1 in the same cohort as Cambridge-bound UK students, consistent with his later move to Trinity College Cambridge.Dec 2019
• Credited as a problem solver in the '2018 Thailand TST Solutions' document, the strongest evidence of his participation in Thailand's 2018 olympiad selection (TST) in addition to the 2019 IMO.Jan 2018
