T2 Field-leadingMilestone (age 25)
Co-created React Native on Facebook's original team (public 2015, ~age 25), helping define cross-platform React mobile development; earlier popularized CSS-in-JS ideas.
French EPITA CS graduate who joined Facebook around 2012 right after school. Worked Photos then frontend platform; helped build React Native core components/Animated, popularized CSS-in-JS, later brought Prettier to widespread use and created Excalidraw.
Starting point
Born ~1990 in France; specialized CS training at EPITA then immediate Facebook hire.
Current position (2026)
Long-time Meta frontend engineer; co-creator of React Native and Prettier; creator of Excalidraw and major CSS-in-JS ideas.

Dominant figure at the top of a field. The tier summarizes documented career recognition through the data cutoff—not Christopher Chedeau's worth or future potential.
Question four · where did the leverage come from?
Christopher Chedeau'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 Christopher Chedeau'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, Christopher Chedeau's starting-advantage total is at the 86th percentile. Separately, their built or converted leverage total is at the 92th 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
Reactiflux AMA (2016) places FB join ~4.5 years earlier (~2012) after EPITA. React Native public launch 2015 is the clear material ≤26 platform milestone; CSS-in-JS talks and later Prettier/Excalidraw extend the trajectory. Birth year 1990 is CSV-estimated and consistent with EPITA→FB 2012 timeline.
