Sven Rogge · Independent web developer · Kassel

Websites and automations,
built for small businesses and individuals.

A website your team can update. Less time spent on repetitive admin. I build both, working directly with you from the first conversation to launch.

What I can help with

A better website. Less busywork.

Hire me for either, or bring them together in one project.

A website you can run yourself

Make it easy for customers to understand your business and get in touch. Keep your content current without calling a developer for every change.

  • Design and development, from first layout to launch
  • Content editing for your team, with a practical handover
  • Mobile-friendly pages, accessibility and search foundations
Starting at €4,000

Less repetitive work for your team

Cut the copying, sorting and chasing between tools. I use regular code for fixed rules and AI only where a task needs interpretation.

  • Sort inquiries and prepare replies for you to review
  • Extract information from documents and move it between tools
  • Logs, safety checks and agreed human approval steps
Starting at €2,000

Who you’ll work with

You talk to me.
I build it.

I’m Sven, a freelance developer with ten years of experience building for the web. I help you work out what the software needs to do, explain the options in plain language, and handle the technical work.

  • Direct contact. The person answering your questions is the person doing the work.
  • Experience I’ve spent ten years building web products and workflows for clients. I help you work out what the software needs to do, then build it.
  • Working versions early. You can try things while there’s still time to change direction.
  • Code you can maintain I work with TypeScript, Svelte, Node, and SQLite or Postgres. I build for speed, security, and growth, with code that another developer can read and maintain.
  • A proper handover. You get the code, access and documentation to keep going—with me or another developer.

Selected work

How it works

From first call to handover.

We agree on the scope and price before I build. You stay involved throughout and aren’t tied to me after launch.

  1. A free 30-minute call

    Tell me what’s getting in the way. We’ll discuss whether I can help before choosing any technology.

  2. A fixed-price proposal

    You get the scope, fixed price and timeline in writing before committing. Work starts once you approve it; changes to the scope are agreed separately.

  3. Build and review

    I share a working version and check in weekly. You try it, ask questions and help shape what comes next.

  4. Launch + 30 days of free care

    Your website or automation goes live with a proper handover. For the first 30 days, bug fixes and minor adjustments within the agreed scope are free. New features are quoted separately.

Before we talk

A few useful answers.

How much does a project cost?

A website with content editing starts at €4,000. A focused automation starts at €2,000. After our first call, I’ll send a fixed-price proposal for the agreed scope.

Do I need to be technical?

No. Tell me what you want to improve in your business and show me how you work today. I’ll explain the options and trade-offs without expecting you to choose the technology.

Which CMS should I use?

For new sites, I usually recommend Sanity for editorial teams, Strapi if you want to self-host, or headless WordPress if your team already uses it. I’ll connect your site to whichever CMS suits you best.

Can you work with our existing tools?

That’s the starting point. We’ll look at your website, content system and business tools first, then check what can be connected or improved before replacing anything.

Does every automation need AI?

No. Fixed rules are often faster, cheaper and more predictable. I use AI for tasks such as interpreting an inquiry or extracting information from a document, with human review where needed.

Is AI automation safe for my business?

Every automation I build includes logs and safety checks. A person reviews the output before anything is sent, unless you explicitly choose to skip that step.

How do you handle business data?

Before building, we agree what data the workflow needs, where it is stored and which providers can receive it. We can choose EU hosting where appropriate, limit access and define approval steps before information is sent or changed.

What happens after the first 30 days?

You can choose a monthly care plan or hourly support. You’re not tied to either. The initial care period covers bug fixes and minor adjustments within our agreed scope, not additional features.

Can you take over an existing project?

Often, yes. Send me a website or staging link and explain what needs attention. If a code review would help, we can arrange access privately.

Let’s talk

What would make work easier for your business?

Book a free 30-minute call. Bring a website idea or a task you’re tired of doing by hand. We’ll work out whether I can help—no technical brief needed.
