• Quant employment verification: CONFIRMED. Identity is supported (same name across LinkedIn, personal site, GitHub and IMO records), and he has held actual roles at two quantitative trading firms: DRW (London, Software Engineer, Jul-Aug 2024 - market-data labelling library in C++) and Qube Research & Technologies (Quantitative Developer Intern Sep 2025-Feb 2026, then Quantitative Developer Mar 2026-present). Both employers operate in quant finance: QRT's own site describes it as a 'global multi strategy investment manager'; DRW describes itself as a 'diversified trading firm'. AMD (2023) is a semiconductor company, not quant finance.
• Identity is corroborated across four sources sharing the same name: LinkedIn (ahsanalmahir; Oxford; Maths & CS), the personal site anglypascal.github.io ('prospective undergraduate of Mathematics and Computer Science in The University of Oxford'); the GitHub account AnglyPascal (display name 'M Ahsan Al Mahir'); and IMO records for Bangladesh 2019/2020.2024
• Qube Research & Technologies is a quantitative hedge fund - its site calls it a 'global multi strategy investment manager' deploying strategies 'across geographies, asset classes and time frames' - so the employer classification is quant finance, not a name-only match.
• Career timeline (index-derived from the LinkedIn record, not independently primary-sourced): AMD Software Engineer Intern 2023 (Cambridge); DRW Software Engineer Jul-Aug 2024 (London); QRT Quantitative Developer Intern Sep 2025-Feb 2026; QRT Quantitative Developer Mar 2026-present.
• DRW is a proprietary trading firm ('a diversified trading firm innovating across both traditional and cutting-edge markets'), confirming a genuine trading-finance employer.
• IMO 2019 (Bangladesh): Bronze, rank 168, 22 points (P1 7, P2 6, P4 7, P5 2). IMO 2020 (Bangladesh): Bronze, rank 227, 20 points (P1 7, P4 7, P5 6).
• The DRW stint is ~1 month (Jul-Aug 2024) although the title reads 'Software Engineer', which matches an internship-shaped engagement rather than a full-time role - a label that would mislead if taken at face value.
• Runs 'ahsan's island', a personal site/blog where he teaches olympiad mathematics - a 12-week 'Advanced Training for Olympiad Mathematics', a 10-week beginners' course, and a BdMO crash course, the latter two in collaboration with other olympiad students.2024
• Named to the six-member Bangladesh team for the 60th IMO (2019) while a student at SOS Hermann Gmeiner College, Dhaka.May 25, 2019
• AMD is a semiconductor company, not a quantitative-finance employer; the 2023 firmware internship for a low-latency network adapter is hardware engineering.
• The GitHub account AnglyPascal hosts 'MO-Problem-Journal' (59 stars, 6 forks), an olympiad problem index organized by sub-topic, alongside software projects atlas, fintracker, scalite and sty.
• Listed as co-author of 'Master the MAT' (Oxbridge Mind) on a UK retail listing - a MAT (Oxford Mathematics Admissions Test) preparation book, consistent with his Oxford maths admissions path.
