• Quant employment verification: UNRESOLVED. Identity is supported: the LinkedIn profile linkedin.com/in/todor-markov self-describes as a Bulgarian IMO 2012 medalist educated at Sofia High School of Mathematics and Illinois Institute of Technology, matching the Olympiad subject. A role 'Quantitative Researcher, WorldQuant LLC (Sofia), 2018' with description 'Designed and implemented automated trading algorithms' appears on that profile. WorldQuant LLC is a genuine quantitative investment firm (systematic/algorithmic trading). However this role rests solely on LinkedIn-derived enrichment (index-sourced), with no independent primary-source confirmation and only a year (2018) rather than dates; per source policy, index-only employment is retained as uncertain. WorldQuant's separate 'WorldQuant BRAIN' online research program is a competition/student platform and does not by itself establish employment.2018
• Distinct from the US-based AI researcher also named Todor Markov (DeepMind/Anthropic-affiliated work); same name, different person, do not merge their records.2026
• Senior Researcher at Zimperium designing algorithms for whitebox cryptography, listed as current since 2022 and the newest role on the profile; if accurate, he is not in a quant role today.2022
• Competed for Bulgaria at the International Mathematical Olympiad 2012, winning a bronze medal (score 15), per the Olympiad results index.2012
• Also associated with an IMO 2012 silver-medal result and an IMO 2013 honourable mention in the aggregated awards; two distinct Bulgarian IMO identities (Todor Sivkov Markov and Todor Mihaylov Markov) are named in the brief, and the merged record may conflate them; identity between the two Olympiad names and the single LinkedIn profile is not definitively disentangled.2012
• Worked as Data Scientist at Transmetrics (Sofia), shipping forecasting and optimization algorithms for logistics and regression analysis for logistics problems, listed on his profile; dates given as 2018-2021.2018
• Reached the ACM ICPC 2016 World Finals competing with Illinois Institute of Technology, an undergraduate programming-competition result distinct from his Olympiad record.2016
• Co-authored machine-learning research published on arXiv, and is named on US patent 10,992,156 B2 for autonomous screening and optimization of battery formation/cycling procedures.2022
• Worked as Data Scientist at Adcash (Sofia) on advertisement-selection optimization, machine-learning recommender systems and real-time bidding, listed as 2016-2018.2016
• Attended Sofia High School of Mathematics (2004-2012), the standard Bulgarian olympiad pipeline school, then earned a BSc in Applied Mathematics at Illinois Institute of Technology (2012-2016) and an MSc in Mathematics at Sofia University St. Kliment Ohridski (2020-2022).2012
• Uses the handle 'mTogop'/'Togop' on competitive-programming platforms (Topcoder/Codeforces) and 'todor-markov' on GitHub, cross-linking his competitive and open-source presence.2016
• Maintains a personal site at todor-markov.github.io linking his GitHub and professional identity.2023
