Heuristic UX Audit for Bookbibuli

A heuristic accessibility audit of Bookbibuli, a children's reading platform. Uncovering how hidden assumptions in form logic silently exclude real users, and how a JavaScript-only architecture blocks access for everyone who relies on assistive technology. FINDINGS: Eight issues were identified and prioritised by severity and user impact. The two critical findings were structural as in they affect every user on every page, and they interact directly with accessibility. WHAT I EVALUATED: I structured the audit across five flows - New user onboarding, Content discovery, Reading Experience, Account management and Accessibility evaluation against WCAG 2.1 AA - each assessed against Nielsen's 10 heuristics.
