Frequently Asked Questions About Web Development

No, I AIM for it. I optimize code, images, caching, and build on fast frameworks (Next.js, Astro). But: If you later add large images, videos or external scripts (e.g., chat widgets, analytics), the score drops. I deliver a solid foundation – but no guarantee for permanent 90+.

No. I develop responsively with mobile focus. This means: Website works on all devices, mobile usage is optimized. But I don't build mobile version first, then desktop version. That's marketing speak. Pragmatic approach: Responsive design from the start.

I develop with Next.js, Astro, React, Vanilla HTML/CSS/JS. For WordPress or Framer, I connect you with partner developers who do this daily and do it better than I could. You get higher quality, I focus on my stack.

Next.js for dynamic, SEO-optimized websites (React-based). Astro for content-heavy sites (extremely fast, minimal JS). React for interactive web apps. Vanilla HTML/CSS/JS + Tailwind for simple landing pages. No backend development (Node.js, databases) - for that I refer you to partners.

Basic SEO (Schema Markup, meta tags, Core Web Vitals optimization) is directly integrated - no extra charge. I don't offer ongoing content SEO or link building myself; on request I can recommend a specialized partner agency.

Simple landing page (5 pages): 2-4 weeks. Business website (10-15 pages, CMS): 4-8 weeks. More complex projects: 8-12 weeks. Depends on your feedback pace and content delivery. No unrealistic '48-hour website' promises.
