- UI Design: High-fidelity mockups on Adobe XD and Figma, interactive prototypes, micro-interactions, design system optimization or creation.
- Testing & Iterations: User testing, mockup reviews, continuous validation with teams, rapid adjustments.
- Product Support: UX/UI documentation, development support, user engagement strategy, post-launch monitoring.
Types of projects:
- Comprehensive ergonomic audit
- Redesign of an existing tool or interface
- Creation of a new digital product
- Journey optimization (web app, SaaS, e-commerce)
My process:I combine ergonomic rigor, design sense, and a deep understanding of user behavior. I design interfaces intended to be learned quickly, used smoothly, and appreciated over time.
