About Nicolas

Leading frontend for over 10 years, my React expertise will help you with the quality of your applications (architecture, scalability, data flow, design system, code organization) as well as the efficiency of your user experiences (UX, UI, accessibility).
Whether it's a new project or an existing codebase, I can create your product or participate in its improvement.
Finally, I collaborate very closely with all stakeholders (Backend, CPO, Designers, CSM, Sales) to better understand problems and provide solutions that will have a positive impact on the product and business.
