From first idea to a site that runs.

One point of contact for design, development and maintenance, so your site stays fast, secure and up to date.

    Fast, modern websites built to measure. From a simple business site to custom work, using the latest techniques.

  • App development with AI

    Web and mobile apps from concept to launch, including smart AI features. Like IntervalCoach, an AI training platform for athletes.

  • Hosting & security

    Reliable WordPress hosting with updates, security and maintenance, so your site stays fast and safe.

About me

I've been building for the web since 2010.

I am Martijn Russchen. What started in 2010 with video production has grown into what I enjoy most today: building websites and apps, and then hosting and maintaining them reliably.

I have contributed to open source for years, including react-datepicker, used by countless developers worldwide. I bring that experience to every project. IntervalCoach, my own AI training platform, grew out of my passion for cycling and data and shows how I put AI to work in real products.

Security is my trade: with a background in security and years of WordPress experience, I keep sites safe, fast and up to date.

You work directly with me: one dedicated point of contact who thinks along, from first idea to launch and everything after.
