Web development shouldn't be this painful

Agencies quote months of work and budgets that make your eyes water. Then deliver something you can't easily change yourself. The old model is broken.

Agencies quote astronomical budgets for basic sites

Months of back-and-forth before anything goes live

🔒

Locked into platforms or vendors you can't escape

The result is slow, hard to update, and already outdated

FAQ

Frequently asked questions about Web Development | J.Cubiró

Everything you need to know about modern web development

Two reasons: AI-powered development tools dramatically speed up coding, and I work solo with no coordination overhead. No project managers, no ticket queues, no meetings about meetings. Direct communication and fast iteration.

Primarily Astro for marketing sites (incredibly fast), React or Next.js for web apps, and Tailwind CSS for styling. The stack is chosen based on your needs—never the other way around.

Absolutely. I integrate headless CMS solutions (like Sanity, Contentful, or Storyblok) so you can edit text, images, and pages without touching code.
