Notes2

• Quant employment verification: CONFIRMED. Citadel Securities LLC is an electronic market maker / trading firm (quantitative finance). Brian Bi's own resume states an actual role: 'Citadel Securities LLC - Software Engineer (08/2018-03/2021)', on the Low Latency Engineering team (market-data processing) and the ETF Tech team (deploying parameters to trading strategies). Identity is supported: the resume's achievements (IOI 2009/2010 silver, ICPC 2011) and projects (wcipeg PEG Judge) match the target. The role is software engineering at a quantitative trading firm, not a quant-researcher/trader title; employer classified as quantitative finance (market making). Not a student program.
