- Ensure multi-language support (i18n) is consistent, complete, and maintainable.
- Improve accessibility (WCAG compliance) and performance (Core Web Vitals).
- Guide the mobile application evolution.
- Collaborate with backend and AI teams to design clean API contracts and data flows.

- Proficiency with modern CSS (SCSS, CSS Grid, Flexbox), responsive design, and cross-browser compatibility.
- Excellent written and verbal communication skills in English.
#PreferredSkills
- Proficiency with Figma or similar design tools for wireframing and prototyping.

- Knowledge of accessibility standards (WCAG 2.1+).
- Experience with internationalization (i18n) frameworks and multi-language applications.
- Familiarity with conversational/chat UI patterns — streaming text, markdown rendering, rich embeds.
