About Julien

Looking for a senior frontend developer who can transform your ideas into high-performing, fluid, and maintainable web applications?

With 8 years of experience in web development (including several freelance projects and consulting environments), I work on various projects, from creating modern interfaces to optimizing performance on existing applications.

💻 What I do:

  • Development of frontend applications with React, TypeScript (and modern frameworks)
  • Integration of pixel-perfect interfaces from mockups (Figma, etc.)
  • Performance optimization (loading time, UX, SEO)
  • Implementation of best practices (clean code, architecture, testing, code review)

🚀 My added value:

  • Strong attention to user experience and details
  • Clean, maintainable, and scalable code
  • Ability to quickly understand product challenges
  • Autonomy and clear communication

🌍 Organization & remote:
Currently based in Australia, I work remotely daily with international product teams and clients. Accustomed to remote work, I am comfortable with collaborative tools and distributed environments.

I am available for freelance missions, remotely, in French or English.
