• Quant employment verification: CONFIRMED. Identity is supported across independent sources (Stanford resume, IOI 1989 record, DBLP, Facebook patents). Employment evidence: the resume documents an actual full-time role as Senior Software Developer at Marketcetera, Inc. (2/2008-12/2009), building core components of the Marketcetera Open Source Algorithmic Trading platform including the order routing server (ORS) re-architecture. Employer classification: Marketcetera was a trading-technology software vendor whose product was an algorithmic/automated trading platform - it operates in the systematic/algorithmic-trading space but is NOT an investment firm, hedge fund, market maker, bank, or asset manager, and his role was software engineering on trading infrastructure rather than quantitative research or strategy execution.
