Three areas where I go deeper than most
I've been building web projects since 1999. These three areas are where I currently make the difference – and probably why you're here.
01
AI Visibility
So your website gets cited by ChatGPT, Perplexity and Claude – not just ranked on Google. Structured data, llms.txt, schema markup, semantic architecture. Built in, not bolted on.
Proof: This website itself, as a live technical test. Generative Engine Optimization (GEO) and Agent Visibility Optimization (AVO) aren't buzzword bingo – they're measurable disciplines.

02
BFSG Compliance & Accessibility
Since June 2025, B2C websites in Germany must be accessible. Fines up to €100,000. I build WCAG 2.1 AA compliant – as an update for existing sites or from scratch.
Proof: Impact Report of Seniorpartner in School, professionally and accessibly built. Quote from the chairwoman's Google review.

03
Shops & Custom Solutions
WooCommerce with B2B features, dealer portals, custom plugins. When standard isn't enough, I build what's missing – clean, documented, maintainable.
Proof: Gerwing Steinwerke, one of Germany's largest paving stone manufacturers. Custom stone sample tracking, B2B dealer portal, price groups. Built alone, sole technical responsibility since 2023.

★★★★★
BFSG & Accessibility
Seniorpartner in School is a nationwide social organization. A well-designed digital impact report is important for our work. Jan-Erik and the competent copywriter Annemarie set up this new format for us professionally and accessibility-friendly. Great teamwork, reliable and dedicated. SiS says THANK YOU!
★★★★★
Long-term collaboration
Professionally, I've worked with various media designers and I'm glad to have found a reliable partner in Andersen Webworks for several years now. Professional web design that always surprises me – my ideas are taken seriously and given the final touch by Mr. Andersen. That's how you stand out from the competition!
Process
No pitching marathon. One short call shows if we're a fit.
1
Initial call (free)
A call – video preferred. What do you need, what do you have, what's the goal? After that, we both know if it's a fit. No sales pitch, no obligation.
2
Concept & Quote
I develop a concept with structure, page layout, and technical approach. Then you get a concrete offer with scope, price, and timeline. You know beforehand what you'll get.
3
Implementation
I build. You get progress updates. Change requests are implemented directly – short paths, quick response.
4
Launch & Maintenance
Site goes live. After that, I'm still there – for updates, changes, problems. Or clean handover: you're never locked in with me. View maintenance packages →
Pricing
Fixed price after the first call. No nasty surprises.
All prices net. Hourly rate: €80/h. All packages & details →
Free consultation →FAQ
The four questions that come up in every initial call. Answered upfront.
How long does a typical project take?
It depends on scope – but significantly faster than with an agency because there are no coordination loops in between. You'll get a specific timeline estimate after the initial call. I'm usually available within two weeks.
What happens if you get sick or go on vacation?
All my projects run on standard technology (WordPress, WooCommerce, HTML/CSS/JS). Everything is documented. Any other developer can take over my work – no proprietary system, no vendor lock-in.
Can't ChatGPT just build my website?
AI can generate code. What it can't do: understand what your business needs. A website isn't just HTML – it's strategy, structure, user guidance, legal compliance (GDPR, imprint, BFSG), ongoing maintenance, and someone who is responsible when something doesn't work.
What sets you apart from other freelancers?
Three things. First: 27 years of experience, including three years of professional QA in the games industry – I find bugs before your customers do. Second: I maintained the entire web presence of a corporate group with eleven websites on my own for two years. Third: My wife is a professional editor. Every text is professionally proofread. Most freelancers deliver code. I deliver a finished product.
