Shu Ding
Milestone (age 25)
Created SWR with Guillermo Rauch in 2019 (~age 25), the first major hook-based stale-while-revalidate data-fetching library; also joined Vercel early (2018) and designed the Next.js website.
Chinese algorithm-competition / web background; BSc CS Fudan 2017, Microsoft engineer, then joined Vercel/ZEIT in 2018 as an early engineer. Built SWR (2019), Nextra (2020), later major Next.js architecture (Streaming SSR, RSC), Satori, AI SDK pieces, and co-created v0.

Question four · where did the leverage come from?
Shu Ding's leverage provenance
Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Shu Ding's outcome attributable to any origin.
Luck is not a leftover score.Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.
Within Researchers / independent engineers, Shu Ding's starting-advantage total is at the 74th percentile. Separately, their built or converted leverage total is at the 92th percentile. Other T3 profiles average 7.0 / 24 starting advantage and 11.7 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.
