Jianzhi Wang

Jianzhi Wang is a mathematics student whose public footprint is anchored by a GitHub account (github.com/jianzhi-1) and a personal site (jianzhi-1.github.io) that both name him and show a New York, NY location, plus UC Berkeley coursework repositories (math-ucb, cs61a, physics-notes) and a Devpost portfolio listing UC Berkeley, Berkeley, California. Contact aggregators additionally associate the name with University of California, Berkeley (2021-2025) and Raffles Institution (GCE A Levels). Aggregator listings describe a quantitative-researcher internship lead at Jump Trading Group and show an Optiver-domain email, but these are index-only and conflicting, and the bare LinkedIn slug is ambiguous; no primary source read here confirms any quant-finance employment. Identity is supported for the UC Berkeley / GitHub / personal-site cluster; quant employment remains unverified.

Notes5

• Quant employment verification: UNRESOLVED. No primary source read this run establishes an actual past or present role or internship for this Jianzhi Wang at any quantitative-finance employer. The only employment evidence is two contact-aggregator listings (index-only, not independent primary-source confirmation): ContactOut (contactout.com/jianzhi-wang-91787) labels him 'Quantitative Researcher Intern' at Jump Trading Group and also surfaces an Optiver-domain email, while RocketReach (rocketreach.co/jianzhi-wang-email_411295764) places him at Jump Trading Group in Berkeley, CA. The two aggregators conflict (Jump Trading vs Optiver), and enrichment of the bare LinkedIn slug linkedin.com/in/jianzhi-wang returned an unrelated employer (SHARE INDIA), so the LinkedIn handle is ambiguous and cannot be treated as this person's profile. Employer classification: Jump Trading Group is a proprietary trading firm and Optiver is a market-making firm, both genuine quantitative-finance employers, so a confirmed role at either would qualify - but with the identity only aggregator-supported and no role verified from a primary source, employment is unresolved rather than confirmed or ruled out.
• Contact-aggregator listing (index-only, not primary-source confirmation) describes Jianzhi Wang, Berkeley CA, as 'Quantitative Researcher Intern' at Jump Trading Group.
• Separate contact-aggregator listing (index-only) places Jianzhi Wang at Jump Trading Group in Berkeley, CA and gives education as University of California, Berkeley 2021-2025 and Raffles Institution (GCE A Levels, H2 Physics/Chemistry/Math).
• ContactOut snippet shows an Optiver-domain email ([contact omitted]) alongside the Jump Trading Group role, so aggregator sources conflict on whether the current employer is Jump Trading or Optiver; treat both as unverified leads.
• GitHub account github.com/jianzhi-1 is named Jianzhi Wang, lists location New York, NY, and links the personal site jianzhi-1.github.io; repos include 'math-ucb' (UC Berkeley mathematics notes), 'cs61a', and 'physics-notes', tying the account to a UC Berkeley math student.
• Index enrichment of linkedin.com/in/jianzhi-wang returned an unrelated employer (SHARE INDIA), indicating the bare LinkedIn slug is ambiguous and must not be trusted as this person's profile without further matches.
• Devpost portfolio for jianzhi-1 lists UC Berkeley and Berkeley, California, and skills python/c++/java, corroborating the UC Berkeley identity; hackathon projects include LLMaOS and AI Member of Parliament.
