• Quant employment verification: CONFIRMED. Jane Street, the employer, is a proprietary trading firm and market maker whose business is quantitative finance (systematic/algorithmic trading in equities, bonds, commodities, FX), so the employer classification as a quant-finance firm holds. Employment evidence: the subject's own CV (erekle.uk/cv) and personal website (erekle.uk) both list a 'Jane Street trading intern' role, and this is an actual internship (the profile describes it as a 'Full trading internship + one week software bootcamp'), not a student program or insight day. Identity is supported independently: the CV, personal site, LinkedIn, IOI stats page and Codeforces all describe the same Cambridge CS / IOI competitor. Limitation: the role and its 'Quantitative Trading Intern' title and the 2025 dates come from LinkedIn-profile enrichment of linkedin.com/in/erekle-roi, i.e. an index-derived profile; the CV/site confirm the internship exists but do not themselves state the exact dates, so dates should be treated as index-derived.
