• Quant employment verification: CONFIRMED. Identity is supported (LinkedIn headline 'ex-Jane Street Capital', IOI 2012/2014 profile for Croatia, and a Toptal verified engineering profile all describe the same Zagreb FER software engineer). Employment evidence: a Trading Systems Internship at Jane Street Capital, London, in 2017 (RPC-to-Kafka migration, live trading view, ETF trading-obligation verification) - an internship at a global proprietary trading/market-making firm, i.e. quantitative finance. Additional trading-sector work: Daxom Capital (2020-2021) building a post-trade analysis/order-routing app for a firm with ~$500M-1B daily turnover, and Tallarium (2021-2022), an OTC energy-markets data/analytics platform. Employer classification: Jane Street = market maker/prop trading (quant) -> qualifies; Daxom Capital = trading firm (role is trading-tech, 'quant' depth unconfirmed); Tallarium = energy-trading data vendor. These are actual roles/internships, not camps, insight days, competitions or offers; the internship dates come from the Toptal resume and the LinkedIn index, not a Jane Street primary page.
• Daxom Capital (2020-2021), full-stack developer: led a post-trade analysis app (position hedging, profit calculation) where daily turnover was ~$500M-1B, improved margins via smart order routing, cut reporting latency ~50% via Kafka - trading-technology work at a trading firm; quantified-research depth is not established by the source.2021
• Jane Street Capital, London (2017), 'Trading Systems Intern': migrated old OCaml RPC to Kafka, improved the live trading view, and developed software verifying ETF trading obligations.
