About Juliette

juliette-prodesign.com
I am a Product Designer with 3 years of experience in digital design, specializing in creating user-centered experiences that generate real business impact. Coming from a background combining product design and SEO strategy, I have developed a hybrid approach that allows me to boost my clients' traffic and conversion rates.

During my apprenticeship at DiamPark, a healthtech startup, I was the sole internal Product Designer. I led the end-to-end design of a mobile application for patients with Parkinson's disease and a web dashboard for healthcare professionals: user research, workshops, advanced Figma prototyping, Maze tests, design system creation, analytics (Matomo). I contributed to improving adoption and conversion through an iterative, data-driven, and impact-focused approach.

In parallel, my time at Let's Clic allowed me to acquire solid expertise in SEO and SXO. I worked on keyword research, semantic cocoons, optimized content creation, and improving organic visibility. Today, this dual skill set is one of my major assets: I design interfaces that meet user needs and business challenges.

I can assist you with:
• UX Research & UX/UI Design (mobile, web, dashboard)
• Design systems, advanced prototyping, rapid iterations
• Conversion optimization, SXO, ROI-oriented content
• AI integration (chatbots, assistants, automation)
