FWFilip Wolski
Miami, Florida, United States · engineerFilip Wolski is a Polish-born computer scientist and quantitative researcher, born 1987 in Gdansk. Educated at the University of Warsaw and mentored by Ryszard Szubartowski at the Third High School in Gdynia, he represented Poland at the International Olympiad in Informatics in 2003, 2004, 2005 and 2006, winning four gold medals. His career spans competitive programming, embedded software, marine research technology and quantitative finance: software developer intern at Gadu-Gadu (2007), advisor in the Polish Minister of Education's political cabinet (2007-2008), software developer intern at Google (2008), 2009-2010 European Our World-Underwater Rolex Scholar, software development consultant at Liquivision Products (2010-2012), financial trader at Eladian Partners (2012), quantitative researcher at Teza Technologies (2013-2016), research scientist at OpenAI (2016-2020) where he was a core researcher on the OpenAI Five Dota 2 project, and since 2020 senior quantitative researcher at Citadel Securities per his LinkedIn record.
- Quant employment verification: CONFIRMED. Actual quantitative-finance employment is corroborated by a non-index primary/secondary source: a University of Warsaw physics-faculty book preface states that 'between 2012 and 2016' he was 'employed by leading high-frequency trading firms, including Teza Technologies'. Confirmable roles: Eladian Partners, Financial Trader (2012, US-equities HFT proprietary/market-making firm); Teza Technologies, Quantitative Researcher (2013-2016, Chicago high-frequency/proprietary trading firm). Employer classification: Teza Technologies and Eladian Partners both operate in systematic/HFT trading, confirmed independently of the name. The indexed Citadel Securities role (Senior Quantitative Researcher, Miami, from 2020) is index/LinkedIn-derived only and is not separately corroborated, so it is retained but flagged as index-only; it is not relied upon for the verdict. Identity is supported by cross-linked accounts (LinkedIn/GitHub/X/Instagram all 'fjwolski' with a shared self-description) plus the IOI/CPHOF record. No student program, insight day, camp, scholarship, or incoming offer is counted as employment.
- A Polish academic book preface (published by the University of Warsaw physics faculty) states: 'between 2012 and 2016, employed by leading high-frequency trading firms, including Teza Technologies; since August 2016, AI researcher at OpenAI' - an independent, non-index statement of his HFT employment and OpenAI start.
- Employer classification: Citadel Securities is a leading global market maker; his indexed role is Senior Quantitative Researcher, Miami. This is an index-only claim (LinkedIn-derived) and is not corroborated by any primary source found in this run.
- Co-author of 'Proximal Policy Optimization Algorithms' (Schulman, Wolski, Dhariwal, Radford, Klimov, 2017) and 'Dota 2 with Large Scale Deep Reinforcement Learning' (Berner et al., 2019, arXiv:1912.06680), submitting the latter from his own email.Dec 13, 2019
- Won four IOI gold medals (representing Poland) in 2003, 2004, 2005 and 2006; the CPHOF profile records the 2006 result as the first Polish IOI win and an ACM-ICPC 2007 World Finals gold with the University of Warsaw 'Warsaw Eagles' team.Mar 15, 2007
- Core researcher on the OpenAI Five project (deep-RL Dota 2 bots); his own OpenAI newsroom contributor listing includes Szymon Sidor, Jonathan Raiman, Jie Tang and Brooke Chan.
- Identity reconciliation: the index identity 'taiga-30115185' is not referenced anywhere else; identity is instead anchored by the LinkedIn (fjwolski), GitHub (fjwolski), X (@fjwolski) and Instagram (@fjwolski) accounts sharing the identical self-description, plus the IOI/CPHOF competitive-programming record. No conflicting same-name person matches all these signals.
- Career timeline (factual dates): 2012 Financial Trader at Eladian Partners; 2013-2016 Quantitative Researcher at Teza Technologies; 2016-2020 Research Scientist at OpenAI; indexed 2020-present Senior Quantitative Researcher (Citadel Securities). Three of these intervals are electronic-trading roles.
- Student of Ryszard Szubartowski at the Third High School in Gdynia, alongside Jakub Pachocki and Szymon Sidor (both later of OpenAI); Szubartowski is credited with over 100 Olympiad-informatics medalists.Jul 10, 2026

- Google Code Jam 2005 winner.
- GitHub username fjwolski, bio line reads 'AI researcher @ OpenAI, ex-quant trader, software developer, competitive programmer, Rolex scholar and scuba instructor' - a self-described identity bridging OpenAI and quant trading; the same bio text appears on his X and Instagram accounts, cross-linking them as the same person.
