Radoslav Dimitrov

Three-time Bulgarian IOI contestant (bronze 2017 and 2018, gold 2019) and Codeforces Grandmaster now working as a VP on quantitative strategies at The D. E. Shaw Group in New York. Oxford CS graduate with peer-reviewed graph machine-learning research (NeurIPS 2023) and prior internships at QuantCo and Ocado Technology. Runs the personal site radoslav11.com covering his research, competitive-programming work and side projects.

Notes6

• Now Vice President at The D. E. Shaw Group in New York, one of the top quantitative hedge funds -- the classic IOI/ICPC-to-quant pipeline, and the strongest signal of where his competitive-programming skill now pays off.
• Email [contact omitted] is published openly on his IOI statistics profile (alongside his Codeforces and Topcoder links).
• Won a gold medal at IOI 2019 (Azerbaijan) in his final year, after bronze medals in 2017 and 2018 -- the bronze-to-gold jump in the last attempt marks the classic late peak of an elite Olympiad competitor.
• Personal site radoslav11.com is the hub linking his GitHub, LinkedIn, Google Scholar and X (@radoslav11), which cross-confirms those accounts as his.
• Holds a BA in Computer Science from the University of Oxford, where he also worked as a Research Assistant in the CS department.
• Co-authored 'PlanE: Representation Learning over Planar Graphs' at NeurIPS 2023 with Zeyang Zhao, Ralph Abboud and Ismail Ilkan Ceylan -- evidence of a genuine research streak in graph machine learning on top of his contest background.
• Codeforces handle radoslav11 holds the Grandmaster title, and he is profiled on the Competitive Programming Hall of Fame (CPHOF) as the top-ranked Bulgarian coder, index ~0.92.
• Earlier engineering internships at QuantCo and Ocado Technology, plus a stint as an Algorithmic Problem Setter at Musala Soft, show the quant/software trajectory already underway before the D. E. Shaw role.
• Other research projects posted on his site include SGU-Editorial (a dataset of competitive-programming problems with LLM-enhanced editorials), SP-MPNN (shortest-path networks for graph property prediction) and 'Approximate Weighted Model Integration on DNF Structures'.
• Maintains side projects including 'rpai' (an AI agent session manager for tmux) and 'Git LFS Walrus', signalling continued hands-on tooling work alongside the day job.
• Attended Math High School "Acad. Kiril Popov" in Plovdiv -- Bulgaria's elite mathematics gymnasium and a feeder for its national informatics team.
• Runs an old YouTube channel @radoslav11 with tutorials on lesser-known competitive-programming tricks; he jokes he will upload a 4th video if he ever reaches 100k subscribers -- a dormant but existing teaching footprint.
