About Jean-Christophe

Founder of Duplan Studio & Senior WordPress Developer, I help companies, startups, and agencies in the design, development, and optimization of 100% custom, robust, performant, and scalable WordPress sites.

Unlike approaches based on generic themes or heavy builders, I develop clean, maintainable, and performance-oriented WordPress architectures, relying on modern web development best practices.

What I do specifically

  • Development of custom WordPress themes (without builders or with controlled integration)
  • Creation of specific WordPress plugins adapted to your business needs
  • Faithful HTML / CSS / JS integration to mockups (Figma, Adobe XD)
  • Performance optimization, technical SEO, and Core Web Vitals
  • Redesign, migration, or security of existing WordPress sites
  • Evolutionary maintenance and long-term technical support

My added value

  • Clear, documented, and maintainable code
  • Strong focus on performance, security, and user experience
  • Product vision: I develop useful solutions, not just code
  • Fluid communication, respect for deadlines, and complete autonomy

I work on both one-off missions and long-term collaborations, directly with clients or as support for technical teams.
  • French

    Native or bilingual
