He represented Bulgaria at the International Mathematical Olympiad in 2020, 2021 and 2022 and at the International Olympiad in Informatics, winning medals. His listed work history includes software-engineering roles at HedgeServ, an algorithmic problem-setting role at Musala Soft (CodeIT), a Quantitative Technology Internship at Qube Research & Technologies (2025), and a Quantitative Researcher Internship at Xantium Group (Tudor Investment Corporation) starting 2026. Employment details below are from a LinkedIn-derived index unless a source is cited otherwise.

• Quant employment verification: CONFIRMED. Employer classification: Qube Research & Technologies (QRT) is a British systematic/quantitative investment manager (Wikipedia: 'British quantitative investment firm'), and Xantium Group is the quantitative/systematic trading unit of Tudor Investment Corporation, self-described as 'a global multi-strategy investment firm integrating quantitative research with human expertise' trading global markets. The 2025 QRT Quantitative Technology Internship and the 2026 Xantium Quantitative Researcher Internship are genuine roles at quantitative-finance employers, not companies merely named 'quant'. Identity is supported by the index headline ('Maths and CS at University of Oxford, IMO and IOI Silver Medallist, QR intern at Xantium') matching the Oxford CS prize and Bulgarian IMO/IOI record. Caveat: both roles rest on the LinkedIn-derived index profile, not an independent primary-source confirmation.2026
• Awarded the Oxford Department of Computer Science Prize for Mathematics & Computer Science for 2023-24, listed under St John's College - independent primary-source confirmation that he reads Maths & CS at Oxford and was among the department's top students in that year.2024
• Identity cross-check: the index profile's headline ties together three independent facts (Oxford Maths & CS, IMO/IOI silver-medal record, and the Xantium quant internship) that each appear separately in primary sources, making a namesake unlikely.2026
• Described in an April 2023 CodeIT feature as 'a future student at Oxford University' and 'a four-time winner of CodeIT', and named among the three-person task-setting team for the 23rd CodeIT season - placing his Oxford admission in 2023 and a sustained competitive-programming role.Apr 5, 2023
• Won an IMO Silver in 2022 (30 pts) and Bronzes in 2021 and 2020 for Bulgaria, competing all three years; IMO participant id 30236.2022
• Software Engineer at HedgeServ in 2022-2023 and 2024 - HedgeServ is a fund-administration and financial-technology provider to hedge funds, so these are engineering roles at a fund services firm rather than a trading/quant desk; they are distinct from the later QRT/Xantium quantitative internships.2024
• Worked as Algorithmic Problem Setter at Musala Soft (2022-2023), authoring problems for CodeIT; consistent with his presence on the CodeIT 2023 task-setting team and indicating paid, in-domain technical work before university.2023
• Competed at the International Olympiad in Informatics for Bulgaria, taking a Bronze in 2022 (241.41 pts, 99/349); IOI stats id 6468, Codeforces handle Martin53.2022
