Fast, findable websites that convert

I design and build fast websites that rank in Google and in AI search engines, and that are secure by design. SEO, findability and security are part of the work, not an afterthought.

Strong, findable websites

From design and development to findability and security.

Websites & web development

Websites & web development

Modern custom websites with Next.js and React, built for speed and ease of use. From a clean one-pager to a site that grows with you.

SEO, AEO & GEO

SEO, AEO & GEO

Get found in Google and in AI search engines like ChatGPT and Perplexity. Technical SEO, structured data and fast load times as the foundation.

Security & scans

Security & scans

A secure site starts with the basics. I check for the most common holes, from exposed keys to wrong access rights, and fix them before they become a problem.

About me

I’m Danny,
full-stack developer & SEO specialist

I build websites, branding kits and think along on a strategic level to genuinely move businesses forward. Not a website for the sake of having one, but a level of professionalism that saves time, builds visibility or automates and improves an entire process.

My foundation is in enterprise IT. At Concentrix I led the Microsoft VDS team and guided 200+ business customers through cloud, AI and security projects, beating the annual target by 245%. Before that I was an IT manager and built webshops with connected inventory and point-of-sale systems.

That mix of engineering, security and strategy goes into every project. Direct lines, no agency overhead and code you’ll still understand a year from now: you work with the person who actually builds it.

  • Microsoft certified: Azure, 365 and Dynamics (CompTIA Security+ in progress)
  • Full-stack: from a fast frontend to a solid backend, in a modern stack
  • SEO, AEO and GEO built in, not bolted on
  • AI innovator: smart features where they genuinely add value

RevOps

The bridge between strategy and development

My background in sales, CRM and enterprise IT means I speak both languages. I translate commercial goals into working technology: from strategy and RevOps processes to the code that runs them. One person who oversees the whole line, from plan to production.
Process

From idea to live software

A clear process in four steps. No noise, just results.

01

Intro

We talk through your goal, your users and the business case. I think along on the smartest approach. Sometimes that means building less rather than more.

02

Design & scope

I turn it into a concrete plan: scope, stack and timeline. You know up front what you get and what it costs.

03

Build & test

I build in short iterations with previews along the way. Everything is tested on real devices and scenarios.

04

Launch

Live on robust infrastructure. After that I stay reachable for further development and support.
