He studied Computer Science at the University of Cambridge (BA, 2022-2025) and began an MSc in Data Science at the University of Edinburgh in 2025. His listed professional experience comprises a Student Researcher role at Citadel Securities (London, Jul-Sep 2023) on machine-learning stock prediction and a Data Science Internship at Swimlane (Greater London, Jul-Sep 2024) on LLM agent routing.

Notes2

• Quant employment verification: UNRESOLVED. The only quant-finance employment signal is an index/aggregator LinkedIn listing of a 'Student Researcher' role at Citadel Securities (London, Jul-Sep 2023) on ML stock-objective prediction. Citadel Securities is a genuine quantitative market maker, so the employer qualifies as quant finance. However the role rests on the index/aggregator alone (no independent primary-source confirmation of the employment), and a 'Student Researcher' program title is a student program, which does not by itself establish employment. Identity is supported by IMO official records (Sviatoslav Denyskov, Ukraine, IMO 2021/2022) but the employment link to that identity is not. Classification: candidate employer = quant market maker (CONFIRMED sector); role = student researcher (student program, unconfirmed). No past/present quant role can be confirmed from primary sources, so status is UNRESOLVED rather than CONFIRMED.2026
• Index-only (aggregator, not independent primary-source confirmation): lists two roles - Student Researcher at Citadel Securities (London, 2023) on ML stock-objective prediction (CatBoost/XGBoost/Python), and Data Science Intern at Swimlane (Greater London, 2024) on CoT/ReAct LLM routing (Python, langchain/langgraph).2024
• IMO official results confirm identity: Sviatoslav Denyskov competed for Ukraine at IMO 2021 (silver) and IMO 2022 (silver); this is primary-source identity evidence independent of the LinkedIn index.2022
