Back to original languageAbout Théo
Frontend developer specializing in React, TypeScript, and Tailwind CSS, I support product teams in the design and evolution of complex web applications.
For over 2 years, I have been working in startup environments (Pecule then Fraktion), where I participated in the development and improvement of SaaS products in production.
My work has primarily focused on business-critical interfaces:
• Complete redesign of user onboarding flows
• Improvement and optimization of subscription funnels
• Development and redesign of client and administrator dashboards
• Structuring and improvement of data tables (clients, subscriptions, etc.)
I pay particular attention to interface clarity, application performance, and code maintainability.
In addition to my frontend experience, I have also worked on personal projects involving backend development (Node.js, REST API, databases), which gives me a better understanding of the overall constraints of a web application.
I can assist with:
• React / Next.js interface development
• Integration of Figma mockups into production-ready interfaces
• Creation of dashboards and internal tools
• Improvement of user journeys and conversion
• Refactoring of existing frontend code
I always prioritize clean, scalable, and easy-to-maintain solutions for product teams.
Feel free to contact me to discuss your project.
