About Nicolas

Developer, architect, and manager for 20 years, I support companies in the design, development, and maintenance of their web projects — primarily on WordPress and WooCommerce.

My approach covers the entire chain: upstream consulting, custom development (plugins, themes, API integrations), deployment, and training for autonomy.
What sets me apart: a demand for service that has become too rare, and a real taste for knowledge transfer. My clients don't depend on me — I make them autonomous.

Some recent achievements:
  • Takeover and maintenance of a park of 30 WordPress multisite sites (NGE)
  • Design of a WooCommerce platform with workshop booking management (AtelierC)
  • Integration of recurring payment APIs for a subscription site (Les Horizons)
  • Operational maintenance and redesign of a network of 5 editorial sites (Mind Media)
Former deputy pole director at Netapsys (35 people), I also have solid experience in team management, technical recruitment, and pre-sales writing.
Always curious, I now integrate AI tools (Claude, Copilot) and automation tools (n8n, Docker) into my workflows to gain efficiency.

Excellent experience with Nicolas who took all the necessary time to explain what he was doing, and how to do the updates myself afterward. Very pedagogical and flexible, and very good customer relations. I recommend!
