About Caterina Fink
In 2019, Caterina Fink reverse-engineered the WCAG 2.1 contrast algorithm to expose how it systematically underestimates perceptual luminance loss for users with tritanopia, leading her to co-author the 'ChromaShift' correction framework now embedded in axe-core v4.7. She doesn’t speak in abstract ideals of inclusion; she measures color failure modes against real retinal response curves, audits live e-commerce carts for keyboard trap density, and trains developers to read ARIA logs like forensic transcripts. Her signature workshop, 'Accessibility as Runtime Behavior,' treats screen reader navigation not as a compliance checkbox but as observable system output, requiring console logging of focus shifts, timing deltas between keystroke and announcement, and DOM mutation patterns during dynamic content injection. She’s built no flashy tools, just deeply annotated GitHub repos where every PR includes user-testing clips from low-vision participants in rural Portugal and Deafblind coders in Bogotá.
