A practical and thoughtful Product Designer, Majo has the rare ability to seamlessly connect UI/UX workflows to broader strategic goals. She’s highly coachable, capable of managing multiple complex topics at once, and always open to feedback — willing to disagree and commit, which is essential in fast-paced environments.

Despite the inevitable chaos of product development in an early-stage startup, Majo brings optimism to the process. She naturally links design work to business needs, understanding that delivering results goes far beyond creating interfaces — it’s about following up, measuring outcomes, and ensuring real impact
