A site that loads fast isn't left to chance.
Web performance is not a score you try to fake, it's a standard we impose on ourselves: none of our sites goes into production below 95/100 on Lighthouse. It's our minimum, not a negotiable objective.
Behind that score, there are architectural choices: optimized Core Web Vitals, multi-level caching, a frontend that only downloads what the visitor uses, optimized images and real adaptation per platform. Result: your site doesn't load a single useless byte.
Performance is not an optimization you do at the end, it's the starting point. Every technical decision we make is examined from that angle: does it weigh down the load, and does the visitor really need it?
What we put in place
Every byte that loads must earn its place
Performance isn't just measured by the score: we build it layer by layer, from the server response to the final display at the visitor's end.
95/100 on Lighthouse, minimum
None of our sites goes into production below 95/100. It's not a facade objective, it's the threshold below which we don't publish: we fix, we retest, and we only move forward when the score is there.
Optimized Core Web Vitals
Your site is optimized on TTFB, FCP, LCP and CLS. We attack each metric at its source: server response, initial content, main image, stable layout. No faked score, metrics actually measured.
Aggressive multi-layer caching
Redis is used at several levels with smart invalidation: frequently read pages are served instantly, and when content changes, only the content concerned is updated, not everything else.
A frontend that only loads the essentials
Our frontend stack only downloads what the visitor needs, at the moment they need it: JavaScript loads on interaction, not upfront. What isn't used isn't downloaded, it's as simple as that.
Optimized images
Smart sizing, modern formats and progressive lazy loading: the visitor sees a blurred preview during loading instead of an empty space, and no more layout shift when the image arrives.
Real optimization per platform
Beyond mobile first: since mobile, laptop and desktop don't have the same constraints, each platform only loads its own assets. A phone doesn't download desktop images, and vice versa.
