• Collaborate with designers to translate Figma/UX wireframes into high-quality, production-ready components.
• Ensure role-based access control (RBAC) is reflected in the UI across different personas and organizations.
• Write unit and integration tests to ensure reliability and prevent regressions.
• Participate in code reviews, sprint planning, and cross-functional discussions to align with backend and product requirements.
• Contribute to frontend best practices, documentation, and design system consistency.
