Eiffage énergie systèmes

Développeur éco-conception web

Feb 2024 – Mar 2024 · 1 mo · Boulogne-Billancourt, Île-de-France, France · Hybrid

My goal was to create a fully eco-designed website based on pre-established mockups. Here’s an overview of the actions I took:
✅ Reduced the number of page requests to improve performance.
✅ Optimized images using modern formats like WebP, with automatic compression and lazy loading.
✅ Minimized HTML code for a lighter and more efficient structure.
✅ Used CSS for animations and behaviors; JavaScript only when absolutely necessary.
✅ Cached all assets.
✅ Loaded only the necessary styles and scripts per page.
Project results:
A Lighthouse score between 95 and 100 on every page of the site
An A rating on ecoindex.fr
An A rating on websitecarbon.com
