About Julien

Are you looking for a WordPress developer capable of taking your project from start to finish, whether it's a showcase website to be delivered quickly or a more complex development with business integrations? I can help you.

Specifically, I design, develop, and maintain WordPress sites for VSEs/SMEs and white-label web agencies. My goal is simple: to deliver a site that works, is maintainable over time, and meets your business needs — not a generic site slapped onto a purchased theme.

What sets me apart: 8 years of freelance experience, over 100 sites delivered, and about fifty sites under active management today. This volume has allowed me to industrialize my workflow, which translates into short deadlines and controlled budgets for you.

The types of projects I regularly work on:

— Creation and redesign of WordPress sites (showcase, business sites, editorial platforms)
— Custom business software development, intranets, and internal platforms
— Custom WordPress plugin and theme development
— API integrations: SSO ID.NOT, payment gateways (Mollie, Stripe), ERP connectors, and third-party services
— WooCommerce: stores, booking systems, custom payments
— Custom Gutenberg blocks
— Evolving maintenance and long-term support

I also develop in React and Next.js when the project requires it.

Available for one-off missions, recurring agency partnerships, or long-term support. To discuss your project, contact me directly.
