PROFILE

Eliot Pontarelli

Worked on the facebook/react repository to enhance the React compiler by enabling correct ref access within event handlers on built-in DOM elements. Developed the enableInferEventHandlers feature, allowing the compiler to infer event handler types for JSX props on primitive tags, which prevents render-time errors when accessing refs in callbacks. This solution involved deep compiler development, including AST analysis and integration with TypeScript and Flow for improved static analysis and type inference. The work improved type safety and developer experience for both React core and downstream libraries, demonstrating a strong grasp of React internals and advanced JavaScript and TypeScript engineering.

November 2025: Core compiler enhancement for React enabling correct ref access in event handlers on built-in DOM elements. Implemented enableInferEventHandlers to allow the compiler to infer event handler types for JSX props on primitive tags, eliminating render-time errors when accessing refs within callbacks and improving type safety for React core and ecosystem.
