• Quant employment verification: NOT CONFIRMED. No role or internship at a quantitative investment, trading, market-making, hedge-fund, or systematic-trading firm appears in the subject's public record. The career history (LinkedIn-derived index) is software engineering and research: Snowflake (SWE and SWE intern), Axiom (ZKP Engineer Intern, Jan-Feb 2025), UC San Diego (Undergraduate Research Assistant), Vector Institute (ML Research Intern), Anyscale, Roblox, BitGo, Dropoff AI, and Wish (SWE Test Intern). Employer classification: Axiom (axiom.xyz) is a zero-knowledge proof / blockchain infrastructure company, NOT a quant finance firm, despite being listed under 'Financial Services' in a company index - a name/index industry tag alone does not establish quant finance. BitGo is a digital-asset custody firm (crypto infrastructure/financial services, not quant trading). Snowflake is a data-cloud company. Anyscale is an AI/ML compute company. None is a quant firm; no trading-desk or systematic-trading role was found. Identity is supported by the IMO contestant record matching the LinkedIn name and the University of Waterloo Indonesia-origin profile, but the employment entries come from a single LinkedIn-derived index and were not independently corroborated.Sep 17, 2026
