Efficient and Practical Web Development
In Web Development, security, clean coding, and efficiency are my top priorities. I write code that not only works but is maintainable over the long term and resilient against attacks.
Where practical, I deliberately avoid unnecessary frameworks and external libraries to keep the code lean and minimize load times. This approach reduces overhead and ensures that your website or web application remains stable even under high demand.
Beyond performance, I follow current web standards to guarantee compatibility and future-proofing with backend systems, as well as all common browsers and devices. This results in projects that are sustainable, easy to expand, adapt, and maintain.
Clear Web Design with a Focus on User Experience
Web Design combines user interface (UI) and user experience (UX) into clear and purposeful communication. Minimalist design ensures clarity and creates space for essential content and functions, allowing visitors to find what they need quickly and interact seamlessly with your website.
This focus on clarity and intuitive user experience effectively supports your goals – whether it’s a contact request, a purchase, or a registration. The design is always tailored to your corporate identity and target audience, ensuring a coherent and consistent overall appearance.
Fluid-Responsive Design, SEO, AEO, and Data Protection by Default
Modern websites must perform optimally on all devices. This is why I consistently implement fluid-responsive web design, which adapts content seamlessly to different screen sizes – from small smartphones to large desktop monitors.
At the same time, I optimize load times to ensure the website performs efficiently even on slower connections. The technical structure is designed so that search engines and AI assistants can reliably index and evaluate content. Data protection and GDPR compliance are fully integrated, with all necessary measures implemented without compromise.
Focus on Core Web Technologies and Strategic Use of Modern Tools
By focusing on core web technologies such as HTML, CSS, JavaScript, and PHP, I maintain full control over the code while keeping it lean and efficient. This adherence to standards allows me to implement new techniques and modern browser features in a deliberate and effective way.
The result is faster load times, enhanced security, and greater stability. At the same time, the codebase remains clear and maintainable, making future updates and expansions straightforward.
Collaboration with Agencies
In addition to managing my own client projects, I support agencies and teams – in Düsseldorf, across Germany, and internationally – as a development partner. I handle technical implementations on behalf of the agency or client and integrate seamlessly into existing workflows.
Thanks to my experience, I can quickly adapt to different requirements and deliver reliable solutions – from backend architecture and frontend design to the development of custom features. I work discreetly while enhancing the agency’s capabilities with solid technical expertise.
Tailored Consulting – The Foundation for Successful Projects
A comprehensive consultation is the first step in every project. The goal is to accurately understand your requirements and collaboratively evaluate technical possibilities, as well as options for design, usability, and SEO. Open and transparent communication ensures you are always informed about the project’s progress and next steps.
Within Düsseldorf, I also offer on-site consultations to discuss your needs personally and directly. Additionally, I can analyze existing projects and provide well-founded insights and improvement suggestions as an external partner – pragmatic and solution-oriented. This structured approach builds trust and lays the foundation for projects that meet your expectations and succeed in the long term.
NUOS – CMS and Development Environment for Complex Web Projects
For most projects, I rely on NUOS, a web system I developed that combines an intuitive CMS with an integrated development environment (IDE) for creating and managing scalable websites and web applications. It allows for both simple content management and the implementation of complex functions – individually or in a team.
NUOS is designed for performance, search engine friendliness, and security. The deliberate avoidance of unnecessary frameworks contributes to its high efficiency. The system also provides tools for user management, media handling, multilingual content, and much more. Its modular structure allows projects to be flexibly expanded and customized – ideal for requirements that go beyond simple websites.

Frequently Asked Questions (FAQ)
1. What budget should I plan for my web project?
For custom-designed websites, costs typically fall in the mid four-digit range. They depend on scope, design, functionality, and technical complexity. More complex web projects with integrations or special requirements usually reach the upper four-digit range, while extensive web applications can require five-figure budgets.
Ongoing operational and maintenance costs usually start at around €10 per month for hosting and from €50 per month for maintenance services. Depending on the scope – including content updates, SEO, monitoring, and other support – these costs can increase accordingly.
2. How long does project completion take?
Simple web projects can often be completed within 2–6 weeks, while more extensive projects may take several months. A detailed timeline is established during the planning phase. Delays are often caused by missing content from clients. To ensure a smooth process, it is important to allow sufficient time for preparation.
3. Which technologies and CMS are used?
Depending on the project, I use established technologies such as HTML5, CSS, JavaScript, and PHP. I primarily work with my self-developed NUOS CMS/IDE – a platform for high-performance, maintainable websites and web applications. It is continuously updated and offers integrated features such as SEO, load time optimization, and multilingual support. Upon request, I can also work with other systems – fully tailored to your requirements.
4. Can I edit content myself later?
With a CMS like NUOS, you can manage content such as texts, images, or news articles yourself. Many routine tasks can be handled without deep technical knowledge, but a basic understanding of layout, design, and web technologies helps maintain a professional appearance and avoid errors. New pages or custom layouts can also be created with some experience or guidance, either individually or as a team.
On request, I can take care of ongoing maintenance and support for your website, ensuring that content remains up-to-date and technically flawless.
5. Is long-term management available after launch?
Yes, I provide long-term management for your project. This includes maintenance, security updates, performance optimizations, as well as technical or content-related improvements. This ensures your website remains secure, fast, and up-to-date.
6. How does the project proceed?
In the initial consultation, we clarify your requirements. You will then receive a customized proposal. Once approved, the concept phase begins, including design drafts that you can review and provide feedback on. I then implement the project technically on a development environment where you can track progress in real time. Together, we prepare for the launch. Throughout the entire process, I keep you regularly informed.
7. Are GDPR and technical standards observed?
Yes, all projects comply with the current General Data Protection Regulation (GDPR) and modern web standards to ensure security and legal compliance. For the processing of personal data, a prepared Data Processing Agreement (DPA) is available. (Note: For final legal verification, consulting a specialist lawyer is recommended.)
8. Do you implement accessible websites?
Yes, I generally design all websites to be as accessible as reasonably possible. Additionally, I implement specific requirements in accordance with German laws such as the Barrierefreiheitsstärkungsgesetz (BFSG) and the Barrierefreie-Informationstechnik-Verordnung (BITV), which comply with the current Web Content Accessibility Guidelines (WCAG). A corresponding accessibility statement is also provided.
9. Do you offer search engine optimization (SEO)?
Yes, basic SEO measures such as clean HTML structure, load time optimization, and semantic markup are included in every project. On request, I also provide advanced SEO consulting and implementation.
10. Do you also take AI optimization into account?
Yes, I take what is known as Answering Engine Optimization (AEO) into account to optimize your website for use by AI assistants. This involves creating the technical foundations with structured data and a clear site architecture that AI systems can efficiently interpret. Additionally, I provide strategic guidance on optimizing your content, building authority, and support the technical implementation.
11. Do you collaborate with agencies?
Yes, I reliably collaborate with agencies as a development partner on client projects – including white-label and project-based work.
