Project Manager / Art Director

Redesign E-Commerce
PrestaShop to Shopify Migration

Outdated design and confusing navigation

Product classification not suited to the French market

No in-house IT team

Complex migration of the loyalty program

[Approach]

To ensure the redesign was both culturally resonant and technically sound, I focused on a strategy that balanced localized expertise with scalable infrastructure.

Cross-Cultural Information Architecture
I assembled a team with deep roots in both Japanese and French cultures. This collaboration was vital in redefining the site’s structure as our primary customer base shifted toward French users. We overhauled the navigation logic to align with local shopping habits, ensuring the product classification felt intuitive to the French market.

Strategic Visual Identity
The design centered on reinforcing brand recognition and trust. I leveraged the brand’s signature “azuki red” to create a cohesive visual thread, paired with high-resolution imagery to emphasize product freshness and reliability.

Seamless System Integration
Beyond aesthetics, I managed the technical transition by collaborating with a specialized development partner in Vietnam. This ensured a successful migration of complex loyalty program data, maintaining customer retention during the shift.

Content Creation & Localization
In a team of three, I defined content needs across the site and contributed to key sections such as the FAQ. I also used AI-assisted translation to support French and Japanese users.

[Skills & Tools]

Experience collaborating with international partners, including successful data migration with a Vietnam-based company

Strong visual design background with a focus on user-centered problem solving
Effective cross-cultural communication and project coordination skills

[Conclusion]

This project, which began as a proactive proposal to the director, marked my first large-scale redesign and major initiative led independently. Without formal UX training at the time, I navigated the uncertainty of the process by relying on a pragmatic, user-focused approach and accessible tools like Shopify. The results were clear: between 2019 and 2024, our online sales grew by 155% (an average annual rate of 20.6%), significantly outperforming the French e-commerce market's growth of 69% in the same period. Ultimately, this experience taught me that a rigorous process, close attention to user needs, and visual consistency are essential to connecting performance with effective design.
