• Quant employment verification: UNRESOLVED. The only employment evidence for Tunan Shi is an anonymized LinkedIn/index record listing three 'Software Engineer Intern' stints at firms redacted as 'Undisclosed Financial Company A' (Jun-Aug 2022) and 'Undisclosed Financial Company B' (Jul-Sep 2023 and Jul-Sep 2024); the employer names, and therefore whether any operates in quantitative finance, are not disclosed and could not be confirmed from any independent source. No Optiver, IMC, Jane Street, Citadel or other quant-firm role was found. Verified identity is strong (Cambridge CS student, IOI 2019/2020 Australia), but the employer classification is unverifiable, so no quant employment is confirmed.
