Major bugs fixed: - Fixed private project creation checks and visibility logic to ensure accurate policy enforcement and UX consistency. - Corrected disabled button state logic for project visibility changes. - Localization fixes: added language declaration fallback and refactored language value imports to prevent regressions. Overall impact and accomplishments: - Reduced policy risk by enforcing policy-driven creation and visibility at both UI and data layers. - Improved localization consistency and onboarding experience for multilingual users. - Enhanced maintainability through centralized policy handling and targeted UI refinements, enabling faster future iterations. Technologies/skills demonstrated: - GraphQL policy checks, React hooks and custom policy hook, i18n/localization practices (useLang, translations), UI polish, and secure external link handling.
