Hi there! I'm Kevin , a UI designer & creative developer, specializing in interface design and web front-end development. From UI/UX design to HTML/CSS/JS integration, I design modern web applications, and create experiences for all screen types.

I've had the opportunity to work with major corporations, startups, agencies, and creatives such as Bêta.gouv and Grist, France TV, Accor, Yousign, Imagile, La Cordée & Checksign. You'll find client case studies further down this page that illustrate my diverse experiences.

I share my work by means of articles, conferences and on my X feeds. Between 2017 and 2018, I organised the cssflip Meetup in Rennes, convening designers, integrators and developers to talk about front-end web topics.

Do you wish to discuss any web issues you may be having with your team? Find out more about my work? Or simply have a coffee and a chat? Feel free to write to me at this address bonjour@kevinbizien.com.

Boom.

Consultancy

I advise and help companies implement cross-cutting design processes. From product design to front-end development, emphasis is put on implementing scalable and maintainable solutions/tools in line with company needs. High-performance CSS architecture ensures appropriate design evolution in the long-term. I help teams communicate better and forge bridges between designers and developers. My goal is always to combine efficacy and quality. Need help implementing a new project? Refactoring an existing project? Let’s get in touch!

Let’s work together

Workshops

I coordinate workshops for companies, as well as various other events focusing on the implementation of high-performance, scalable and maintainable CSS architecture. Having previously discussed specifics, workshops can be customised to adapt to issues relating to an existing project. These workshops cover all good practices from UI/UX design to component integration. Knowing how to efficiently design and cut-out an interface, to then optimally architect a CSS is a huge part of project maintenance. Why not start now?

Rethinking the experience of an open source data tool for the French public sector

Civil servants spend a significant amount of their time wrestling with data: spreadsheets that drift, files that multiply, information that gets lost between departments. Without the right tools, public data remains underused.

Grist changes the equation. This no-code open source tool allows any civil servant to structure their data, create custom views, and share them — without writing a single line of code, without depending on proprietary software. Hosted with full data sovereignty, actively contributed to by France at a European scale, it is a wager on public data as a common good.
