- Experience developing and maintaining design systems, ensuring consistency, scalability, and reuse across mobile products.
- Exceptional attention to detail with a track record of translating ambiguous problems into effective solutions, including using rapid prototyping to validate ideas early.
- Clear, thoughtful communicator who values active listening and intentional collaboration across roles and disciplines.
