Our web agency services
Custom website design
We design and develop custom websites for every need: showcase websites, e-commerce sites, editorial platforms, intranets and extranets, multilingual websites, event websites. Every site is designed for performance (optimized Core Web Vitals), security, accessibility, and SEO from the outset.
We support both large industrial and institutional organizations as Audi, Seat and Dassault Systèmes, as well as SMEs and specialized players as ESCG or the Palace Byblos. This diversity of projects gives us a complete view of digital challenges according to the size and sector of each organization.
Stacks mastered: Custom WordPress, PHP, Symfony, Laravel, Next.js, React, Node.js, and modern headless CMSs. For small projects that we cannot handle in-house, we direct our prospects to a WordPress freelancer, in a logic of complementary expertise.

Our SEO team gets involved both upstream (architecture, structured data, performance) and downstream (content production, netlinking, continuous optimization).
