Freelancer profile translated to English.

Description

For 8 years in Japan, in an international and English-speaking environment, I designed and developed "ax3" from A to Z, a SaaS profiling platform combining neuroscience and marketing, covering every dimension of the project: UX/UI, architecture, back-end, front-end, infrastructure, security, team management, and coordination between design, data science, and neuroscience departments.

Back in France, I am looking for freelance missions where I can bring both solid technical execution and a complete product vision. Remote-first (or hybrid), based near Nantes.
