Vincent Kilchherr - PHP Entwickler Basel

Your Fullstack & AI Developer in Basel

Since 2009 I've been building websites, web applications and backend systems for small and medium-sized businesses in Switzerland. Today my focus is on backend development, AI integration and automation – built on years of experience with real client projects.

No agency structures, no detours. You talk directly to the person who builds your project.

Whether PHP backend with CodeIgniter, Python API with FastAPI or AI integration into existing systems – I find the right technology for your requirements.

I work from my office in Allschwil near Basel and serve clients throughout Switzerland. In-person meetings are just as possible as efficient remote collaboration.

Frequently Asked Questions

Answers to the most common questions about web development and AI integration

How much does a professional website cost?
Costs depend on the scope. Simple business websites, complex web applications and Shopware shops are all quoted individually. Contact me for a free initial consultation and a non-binding quote.
How long does website development take?
A simple business website is ready in 2–4 weeks. Complex web applications or Shopware projects take 4–12 weeks depending on requirements. After our first conversation you'll get a concrete time estimate.
What is an AI-friendly website (GEO)?
GEO (Generative Engine Optimization) means designing your website so that AI systems like ChatGPT, Perplexity or Google AI can understand and cite it. This includes structured data (Schema.org), clear content structure, FAQ sections, llms.txt and strong E-E-A-T signals.
Do you also take over existing websites for maintenance?
Yes, I take over existing websites for ongoing support – regardless of who built them. With an SLA package you get guaranteed response times, regular updates and personal support.
Do you also work with agencies?
Yes, I work as a freelancer for agencies – discreetly and reliably. Whether PHP development, Shopware, TYPO3 or AI integration: I complement your team wherever capacity or specialist knowledge is needed.
