• Quant employment verification: CONFIRMED. The D. E. Shaw Group is a global quantitative investment firm (hedge fund); the subject held a Quantitative Developer Intern role (Jun-Oct 2021) and has been a Vice President in 'Quantitative Strategies' there since 2022, both on the confirmed LinkedIn (Radoslav D., deshaw.com, New York), whose identity is corroborated by the cross-linked radoslav11.com and the IOI/Codeforces handles. Other employers do not add quant-finance roles: QuantCo is an algorithmic data-science consultancy (name contains 'Quant' but is not a trading firm), Ocado Technology is grocery/warehouse automation, Musala Soft is a software company, and Oxford was academic research.Sep 17, 2026
• The D. E. Shaw Group Vice President from 2022 (LinkedIn shows 2022-present, ~4 yrs), New York, described as 'Quantitative Strategies' - a real quantitative finance role at a hedge fund.Aug 1, 2022
• Identity confirmed by a cross-linked loop: radoslav11.com lists GitHub (github.com/radoslav11), LinkedIn (linkedin.com/in/radoslav-dimitrov), Google Scholar and X (x.com/radoslav11), and the IOI stats page for this contestant lists the same Codeforces handle radoslav11 and 'From University of Oxford' on Codeforces.Sep 17, 2026
• Name-collision caution: this is NOT the many other public 'Radoslav Dimitrov' figures that dominate search - a Simon Fraser University international-relations professor (climate diplomacy), a Bulgarian chess Grandmaster born 1993, an NHL/WHL hockey defenceman, and a Bulgaria-based security/AI engineer (bg.linkedin.com/in/radoslavdimitrov, ex-VMware, @stacklok). The subject here is the competitive-programmer/quant developer (handle radoslav11, New York).Sep 17, 2026

• Personal site radoslav11.com is a projects hub with published research and tools: PlanE (NeurIPS 2023), SP-MPNN (LoG 2022), Approximate Weighted Model Integration on DNF Structures (Artificial Intelligence journal 2022), the SGU-Editorial dataset/benchmark, rpai (a tmux AI-agent session manager), git-lfs-walrus, and a competitive-programming Coding Library.Jun 1, 2025
• Career arc reads as competitive-programming -> software engineering -> quantitative development: CodeIT problem setter (Musala Soft, 2018-19) and Ocado Technology algorithms intern (2019) in Sofia, then Oxford CS (BA 2019-2022) with a QuantCo SWE internship and a GNN research assistantship (2020), then a D. E. Shaw Quantitative Developer internship (2021) converting to a full Vice President, Quantitative Strategies role (2022-present) in New York.Aug 1, 2022
• IOI record: bronze at IOI 2017 (rank 135) and IOI 2018 (rank 107), gold at IOI 2019 (rank 21), representing Bulgaria (Plovdiv); high school Math High School 'Acad. Kiril Popov', Plovdiv.Aug 1, 2019
• Employment classification for the quant question: The D. E. Shaw group is 'a global investment and technology development firm founded in 1988' (an established quantitative hedge fund), whereas QuantCo self-describes as a data-science/engineering/economics consultancy ('value from data', founded by four Harvard and Stanford PhDs) - the 'Quant' in QuantCo does not denote a quantitative trading or hedge-fund employer.Sep 17, 2026
• Education: Bachelor of Arts in Computer Science, University of Oxford (2019-2022), after Math High School 'Acad. Kiril Popov' in Plovdiv (2011-2019).Jun 1, 2022
• SGU-Editorial (2025): a dataset of 452 competitive-programming problems with LLM-enhanced editorials that doubles as 'sgu-bench', a deterministic sandboxed LLM/coding-agent benchmark (self-authored, single-author misc. paper) - indicates a current personal interest in LLMs and program synthesis.Jun 1, 2025
• Graph-learning research trajectory 2022-2023 (with Oxford supervisor Ismail Ilkan Ceylan and Ralph Abboud): SP-MPNN (LoG 2022) -> PlanE (NeurIPS 2023, co-author Zeyang Zhao) -> a 2026 ICML AI4Math workshop paper on symmetries for formal theorem proving (co-author Jinwoo Kim). Consistent output across venues rather than a single one-off.Dec 1, 2023
