Investment
Every project is different. This gives you a sense of what to expect.
Your business has no website or an outdated one: customers can't find you, you don't look professional.
Website, restaurant site, or landing page: mobile-friendly, fast, SEO-optimized. Domain, hosting, everything included.
You're online, look professional, and get found.
Your products or services should be bookable or purchasable online, but your shop is slow, confusing, or doesn't exist yet.
Online shop or booking system: WooCommerce, headless, or custom. With payment integration, SEO, and mobile design.
Customers buy around the clock, you sleep.
Repetitive tasks eat your time: answering customer inquiries, managing orders, coordinating staff. This can be automated.
AI chatbot, WhatsApp automation, or custom software that takes work off your plate. AI consulting included.
You focus on what matters, the rest runs automatically.
Standard solutions don't fit: you need a web app, customer portal, booking system, or industry-specific solution built to your requirements.
Custom software from A to Z: concept, design, development, launch. With modern technologies and a focus on maintainability.
A solution that fits your business exactly.

About
FAQ
It depends heavily on scope and complexity. Blanket time estimates aren't serious. After a brief conversation you get a realistic estimate for your specific project.
It depends heavily on scope and requirements, every project is individual. After a brief conversation you get a clear fixed price upfront, no hourly billing and no surprises.
Ideally yes, but I can help with text and also create AI-generated images for you, professional and tailored to your business. For restaurant projects, I'm also happy to work with your existing photos.
I handle small changes like text, images, or opening hours for you. Just send me a WhatsApp message or a quick email. That's included in the support plan from €50/month. You don't have to worry about anything technical, and your website stays up to date.
Yes, I set up hosting, domain, SSL certificate, and email. Everything is included and runs on secure infrastructure.
I offer ongoing support from €50/month: updates, security, backups, and small adjustments. Or I hand everything over to you.
Fair question. That is why I build every project so it belongs to you, not to me. At launch you get all access: your own server, the CMS login and the domain. The code is yours and you can have it handed over at any time. I work with standard technologies like Next.js and WordPress, not a proprietary page builder. So you can switch to a different developer whenever you want, without starting from scratch.
Not at all. I explain everything in plain language and guide you through the process. Most of my clients are business owners, not developers.
Yes! You install a small diagnostic plugin in your WordPress, it takes 30 seconds. This lets me remotely analyze your website: plugins, performance, security, WooCommerce configuration. Then you get concrete improvements: custom plugins, theme adjustments, speed optimization. You can simply delete the plugin after the analysis.
I look at how your business works and find out where AI saves you time or money, for example automated customer communication, intelligent data analysis, or creating text and images with AI. You get no empty promises, just a clear plan of what's possible and what it costs.
