About Serhat

High-Performance Landing Pages: More Leads, €0 Maintenance, Maximum Speed.

Hello, I'm Serhat.As a computer science master's student, I don't build off-the-shelf websites, but specialized high-performance landing pages that convert visitors into real customers.

Why Your Landing Page is Probably Burning Money Right Now:
Most pages are based on slow WordPress systems.

The Result:Long loading times that ruin your conversion rate and constant costs for maintenance, plugins, and security.
My Solution:The Modern "Lead Machine" (Astro.js & React)
I develop landing pages that are technically in the year 2026 – radically fast, secure, and maintenance-free.
Conversion Focused:Every page is built with an optimized, intuitive contact form and clear calls-to-action (CTAs) to generate the maximum number of inquiries for you.
Maximum Speed (Lighthouse 100/100):Your page loads instantly. This leads to better SEO rankings and noticeably lower click prices (CPC) on Google Ads or social media marketing.
€0 Maintenance & Secure by Design:Thanks to my static architecture, expensive database hosting, plugin fees, and the risk of hacker attacks are eliminated. Once built, your page runs without ongoing additional costs.

My Services for You:
  • Individual Landing Page Development:Custom-built single pages including form integration (email, CRM, or WhatsApp).
  • WordPress-to-Astro Migration:I'll migrate your existing landing page to a modern system to double its performance.
  • Core Web Vitals Audit:I'll analyze the bottlenecks of your current page and show you the optimization potential.
Let's eliminate your monthly fixed costs and increase your lead rate.
