About

I am a Senior UI/UX Designer with strong front-end development skills and over 9 years of experience leading digital projects from design to implementation in London and Paris. I have deep knowledge of the end-to-end product lifecycle, from requirements and documentation to design and development. My achievements include opening new revenue streams for a FinTech startup by adding design services, successfully implementing design systems that reduced design and development time, and co-founding a startup where I created a strong brand and developed an e-commerce platform with high customer satisfaction.

In my roles, I have led design system initiatives, collaborated with product teams, mentored junior designers, and managed developers. I excel at bridging design and development to deliver scalable products aligned with user-centered design and accessibility best practices. I am fluent in English and French and have international experience across multiple industries including FinTech, Food Tech, and local government digital services.

Learnings and challenges of building a design system for local government

When launching a new service, speed and consistency are crucial, but without the right tools, teams face inefficiencies and redundant work. I was tasked with creating a design system for Westminster City Council. Collaborating with the Research and Design team, I developed a tool that not only enhanced user experience through consistency and accessibility but also improved team collaboration and product scalability.

More than just boosting efficiency, it transformed how the team works, ensuring every new service delivers a cohesive, high-quality user experience.

This work had several objectives, focusing on team workflows and user experience:

  • Standardising design elements and patterns to ensure a consistent user experience.
  • Establish design and code quality standards.
  • Promote accessibility and document best practices.
  • Improve team communication.
  • Maintain design system standards as it grows.
  • Enhance design and development processes.
  • Enable products to scale more easily.

Implementing the design system reduced the design and build time of new features by 50%

Improve admin user experience by implementing a CMS

I was tasked by ADDB to rebuild Archizest’s website to allow them complete control over their content. We went for the platform Squarespace for its ease of use, however this brought some technical challenges around customisation and special features like a random quote generator or an introduction slideshow. I was able using bespoke Javascript to overcome those challenges and deliver an elegant website that does not feel like it is built on a website builder.
