About Charlyne

Freelance Service / UX / Strategy / Product

💎 Designer with +3 years of experience, I support companies (startups, scale-ups, and large accounts) in designing user-centered digital services and products with high business impact.

🚀 I have worked on various projects (health, retail, mobility, housing, SaaS...): diversification strategies, new service launches, tool redesigns, user research, and experience optimization.

My goal: to design useful, desirable, and high-performing experiences.

🔥 I can support you with:
• Scoping & planning: clarifying objectives, defining methodology and scope.
• User research: creating research protocols, data collection (interviews, observations, usability tests, focus groups, diaries), analysis, formalization, and reporting of findings.
• UX Design: UX recommendations, mapping, journey optimization or creation, collaborative workshops (design and facilitation), wireframes, high-fidelity prototypes, user testing.
• UI Design: design systems, interactive mockups, intuitive and accessible interfaces (Figma expertise).
• Product Strategy: analysis of user and business needs, clarification of product vision, feature prioritization, roadmaps, and design of experiences aligned with business objectives.
• Customer Success: aligning product experience with real user needs and optimizing customer satisfaction.
