GazelEnergie, a leading B2B energy provider in France, relied on an outdated client space that was largely abandoned by users and internal teams, increasing dependency on customer support. As the sole product designer, I led a full redesign in two months alongside the PM and tech lead, rebuilding key user flows, adding mobile responsiveness, and modernizing the UI.

The outcome is a new self-service platform enabling SMEs, industrial clients, and energy managers of purchasing groups to manage their energy contracts autonomously.
