LHannun’s login flow had major navigation issues, especially on mobile screens. My focus was to ensure users could complete this step successfully without interruptions caused by UI or structural problems.

Many users experienced navigation issues during the login process, particularly on mobile devices.This friction often caused confusion, abandonment, and increased support requests.

I was responsible for improving the login experience by redesigning the user flow and interface, ensuring it was fully responsive and intuitive on mobile.

• Research
• Low- and high-fidelity prototyping
• Design system iteration
• A/B testing

I proposed a new structure for the login user flow, redefining the information architecture and visual hierarchy to make the experience clearer and more intuitive.

By mapping the user flow and restructuring the architecture, I was able to establish clearer hierarchies and reduce unnecessary steps.

I then created low-fidelity wireframes to align with developers early on, followed by high-fidelity designs consistent with the existing design system.

The new login flow was tested through A/B testing to compare performance against the previous version.

The results were positive: the updated design reduced user abandonment and improved overall usability.

• One month after implementation, customer service complaints related to login, purchases, and website structure decreased by 75%.
• Based on these results, the login experience continues to be iterated to further improve navigation and usability.

I led the design of Hannun’s UI Kit and design guidelines with a focus on improving user experience and ensuring consistency across the website. The goal was to progressively evolve the interface to retain active users while supporting growth and scalability.

Many users experienced navigation issues during the login process, particularly on mobile devices.This friction often caused confusion, abandonment, and increased support requests.

My main responsibility was ensuring a cohesive user experience while building and maintaining a design system that could scale with the product.

• Competitive benchmarking
• Low- and high-fidelity prototyping
• Design system creation and maintenance
• A/B testing

I proposed a progressive improvement of the website interface rather than a full redesign, allowing the team to iterate without disrupting existing users.

The UI Kit established clear rules for components, typography, spacing, and interaction patterns, enabling faster design decisions and smoother collaboration with development.

A visually focused landing page designed to communicate value clearly and support conversion.

This project was mainly focused on visual design. UX involvement was limited, as the structure and content were already defined.

• Competitive benchmarking
• Low- and high-fidelity prototyping

For this project, I designed a landing page for a new yoga collection. The goal was to showcase large, artistic images that had not been used before. I created an interactive button component with a “+” icon, placed directly on the product images. When clicked, it reveals the product name and price in an overlay, allowing users to click again to navigate directly to the product page. This approach combines visual storytelling with functionality, creating an engaging shopping experience.
