Jeffrey Xiao

Jeffrey Xiao is a software engineer and University of Waterloo software engineering graduate (B.S., 2016-2021, 93.93% cumulative average, Dean's Honour List). He represented Canada at the International Olympiad in Informatics in 2016, winning a bronze medal, after gold at the 2016 Canadian Computing Olympiad. His internships span Yelp (2017), Datacoral (2018), Google (2018) and Cockroach Labs (2019), plus hidden-employer 2020 software engineering internships. His public work centers on distributed systems and data infrastructure (Kademlia DHT in Rust, a WebAssembly NES emulator) and he co-authored the 2019 ACM brief announcement 'Benchmarking Recoverable Mutex Locks'.

• Quant employment verification: UNRESOLVED. Public sources document internships only at technology/data firms (Yelp 2017, Datacoral 2018, Google 2018, Cockroach Labs 2019) and two 2020 'Undisclosed' firms the index does not name; identity is supported (site/GitHub/LinkedIn cross-links; IOI 2016 Canada bronze), but no named employer operates in quantitative investment, trading, market-making, hedge funds or systematic trading, so a quant role is neither confirmed nor ruled out.Sep 17, 2026
• Identity anchor: jeffreyxiao.me resume links [contact omitted], github.com/jeffrey-xiao and linkedin.com/in/jeffreyxiao, tying the personal site, GitHub and LinkedIn to one person.
• Olympiad identity corroborated: he represented Canada at IOI 2016 and won a bronze medal, matching the resume's 'Bronze, International Olympiad in Informatics 2016' entry.
• Distinct namesakes excluded: jeffreyxiao.com is a different Jeffrey Xiao (a University of Pennsylvania CS alum at MongoDB on Atlas Clusters), and a 'Jeffrey Xiao @ Scale AI' LinkedIn profile is a third person; do not merge these into the Waterloo subject.
• Index-only claim: LinkedIn-derived enrichment lists a 'Software Engineer Intern at Undisclosed Financial Institution' (2020) and a second 2020 'Software Engineer Intern at Undisclosed'; the employer is deliberately unnamed, so quantitative-finance classification cannot be confirmed.
• Cockroach Labs internship (backend engineering, New York, May-Aug 2019) was a distributed-database company role, not a quantitative-finance role.
• Four of his named internships (Yelp, Datacoral, Google, Cockroach Labs) are technology/data companies; none operates as a quantitative investment, trading, market-making or hedge-fund firm.
• Education: Bachelor of Software Engineering, University of Waterloo, 2016-2021; secondary school University of Toronto Schools (2010-2016).
• Co-authored 'Benchmarking Recoverable Mutex Locks' (2019), a brief announcement listed on the UWaterloo Distributed Algorithms and Systems Lab publications page, indicating research activity in concurrent/OS systems.
• Won first place at Greylock Hackfest 2017 with 'inSight', an AR headset using ML/image analysis and gaze tracking - an applied ML/CV thread later echoed by his CNN-based scanner/grader at Ivy Global.
• Second place at MIT Battlecode 2017 and fourth at ACM ICPC ECNA Regionals 2016, consistent with a competitive-programming background carried from the IOI/CCC years.
• Public contact: [contact omitted] and phone 1.647.919.3171 are published on his own resume.
