Hi, I'm Gianni, a web developer based in Barcelona, Spain. I help businesses build high-performing custom websites from scratch or transform slow, bloated ones into fast, conversion-focused platforms. I specialize in Astro.js and Tailwind CSS, utilizing a clean, zero-plugin architecture that eliminates heavy bloat and security risks. The result is lightning-fast load times, exceptional user experience, and robust SEO performance. If you value clean code and performance, let’s talk.

FAQ
How much improvement can I expect?
Most sites improve 20 to 50 points on desktop. The exact result depends on your platform and current setup. I give you a realistic estimate before you order.
What do you need from me to start?
Your website URL and the platform you use. For Standard and Premium I need admin access to apply fixes directly. Audit only needs the URL.
Do you work with WordPress?
Yes. WordPress, Shopify, Webflow and custom HTML. I work with all major platforms and can optimize both the code and the hosting configuration.
Will the score stay high after delivery?
Yes, as long as you avoid adding heavy plugins or tracking scripts after delivery. I will explain exactly what to avoid when I deliver the work.
How is this different from a caching plugin?
Plugins apply surface fixes. I find and resolve the root cause: unoptimized assets, render-blocking code, and server misconfiguration that plugins cannot touch.
