Vivien Lecart

As a Freelance Senior Product Designer at Vibe.co, I focused on scaling the user experience for their leading TV ad-buying platform. I partnered with product and engineering teams to transform complex ad-tech workflows into intuitive, self-serve interfaces. My work centered on streamlining the campaign creation process, enhancing data visualization for real-time analytics, and maintaining a cohesive design system to accelerate development cycles.

I built and led the design team from the ground up, growing it from 1 to 4 designers. I defined and drove the design strategy and vision across the company, while also contributing hands-on as the lead designer for the Mobile Squad. I initiated the creation of our Design System to bring consistency and scalability to our product experience.

I was part of the Foundations squad at Payfit, working closely with PMs and engineers to build scalable internal tools and components. I led discovery efforts, conducted user research, and crafted thoughtful design solutions, all while ensuring a high standard of quality, consistency, and usability across the platform.
