Milestone (age 26)

Co-created Redux with Dan Abramov in 2015 (~age 26), establishing the dominant React application state architecture of the mid-2010s.

Prolific React-ecosystem OSS author (Flummox, recompose, redux-router). Collaborated with Dan Abramov on Redux's API and extension points after Abramov started the first implementation for a React Europe talk. Later joined Facebook React core team (Hooks/Suspense/Server Components work) then Vercel.

Question four · where did the leverage come from?

Andrew Clark'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.

Early online platform (2/2)

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Andrew Clark'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, Andrew Clark's starting-advantage total is at the 41th percentile. Separately, their built or converted leverage total is at the 83th percentile. Other T2 profiles average 7.9 / 24 starting advantage and 12.3 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.

Evidence summary

Wikipedia and contemporary sources credit Dan Abramov and Andrew Clark as Redux co-creators (2015). Under CSV birth year 1989 this is age ~26—eligible at the boundary. Later React core work (Hooks/Suspense) is post-milestone career compounding. Family background not documented; peer collaboration and React wave are the main documented advantages.
