One developer. One contact person. No agency bureaucracy — just a direct line to the person building your project from A to Z.

Umutcan Emre Tezgel

Founder & Developer

  • Wetzlar, Germany
  • Sole proprietorship
  • Full-Stack Development

Full-stack developer focusing on high-performance web applications and strategic design — before that, five years of marketing at my father's company. I combine cutting-edge Next.js architecture with uncompromising UX design to create digital platforms that deliver measurable results. At Coday, there is no overhead — you work directly with me, from the initial consultation to launch.

Frequently Asked Questions (FAQ)

How much does a website cost?
We calculate web projects individually based on your specific requirements and provide a binding fixed-price quote on request following a free consultation. You only pay for features and modules that generate tangible business value.
Do you work with WordPress?
No. We believe WordPress is a security risk and performance bottleneck for modern businesses. We build with modern React and Next.js architectures built for strong performance scores and robust security.
Do you offer maintenance?
Thanks to our modern Next.js 15 architecture, websites require no mandatory maintenance contracts. Ongoing technical care, performance audits, and SLA support are 100% voluntary add-ons.
How long does a project take?
A typical high-performance website takes 4-8 weeks. A complex web application takes 3-6 months. We work in 2-week sprints and deliver shippable code every fortnight.
Do you guarantee #1 on Google?
No reputable agency can guarantee #1. However, we build the best possible technical foundation (measured Lighthouse scores, semantic HTML, Schema.org), which is the prerequisite for ranking.
