Senior Product Designer freelancer, AI, SaaS B2B & Complex Data
I design B2B SaaS products where AI and data play a central role. My focus: interfaces that need to make complex things readable: psychometric models, AI chatbots, data dashboards, machine learning signals.
10 years in product design, including 6+ in UX/UI, in software publishing and freelance.
What I do well:
Designing AI products that bring real value, not AI for AI's sake. The latest one (AI Candidate Profile at AssessFirst): 98% adoption in A/B test, analysis time halved, support tickets almost eliminated. On EcoTree, information architecture redesign: +48% leads, +55% traffic, +19% conversion.
My method, end-to-end:
• User research, field interviews, shadowing
• Existing audit + analytics analysis (Mixpanel, Amplitude)
• Information architecture, wireframes, Figma prototypes
• Design system, data visualization, micro-interactions
• User testing, A/B testing, iterations
• Developer handoff and implementation monitoring
On AI: I work on the product layer, not the model. I decide what the system should conclude, how to make these conclusions readable and reliable, and where to keep human decision-making. Conversational patterns, displayed confidence levels, UX guardrails.
What I work on:
Product redesign · AI interface design · Design system · Dashboards & data viz · B2B SaaS MVP · UX research · Accessibility (WCAG AA)
Stack: Figma, Framer, FigJam, Notion, Mixpanel, ChatGPT, Claude.
I work fully remotely from Lyon, and travel occasionally (Paris notably). Available for missions of 3 to 12 months, on a daily rate or fixed price basis.
