More about web design and programming.

During web design, content, navigation and design merge to create a user-friendly and aesthetically pleasing website. Search engines evaluate both the content and technical factors such as structure and performance. Through clever content structuring, intuitive navigation and the targeted use of front-end components, we achieve optimal SEO results. More about SEO.

Barrier-free design maximizes usability for all users. It includes optimizing color contrast, responsive font sizes, clear focus and interaction points, and adaptation for screen readers. Learn more about Accessibility/BITV.

Accessible websites are not only more inclusive, but also increase overall usability. Content is more accessible and navigation becomes more intuitive. More about Accessibility/BITV.

I adapt to the preferences of my customers and have already had good experiences with these CMS: TYPO3, Drupal, graphCMS (Headless Open Source), Bolt CMS (Open Source), October CMS (Laravel-based)

WordPress is a successful CMS that is often used. My specialization in high-performance websites in the areas of SEO, accessibility and impressive special pages requires full control of the frontend code. With the CMS I mentioned, this is possible more directly and successfully. They offer more direct control over the frontend source code and asset pipelines (JS & CSS).

Optimization & Design: ImageOptim, TinyPNG, Photoshop, Figma, Sketch, InVision, Lighthouse, WebPageTest (performance testing), Ahrefs, Moz, PageRanger, Screaming Frog (for SEO analysis)


Rich client applications require a lot of know-how in the front end.

I develop Software As A Service (SAAS) apps for use in the web browser in React. I develop apps for Android or iOS in React Native. I would also be happy to support existing teams in development.

React & React Native

When developing apps, I focus on the frontend written in React, HTML and CSS.

I always work test-driven and appreciate the advantages of web component-based development. I prefer to use GIT, the React Redux UI Binding library, am familiar with JavaScript & ES8 and also work on complex logic and structures.

React & React Native

Comprehensive React expertise

With several years of experience in React, I offer in-depth know-how from component creation to console development.

Optimize your online presence for the best possible visibility.

In today's digital world, positioning on search engines like Google is crucial. In fact, around 90% of all clicks go to the “first page” of Google search results. In order to stand out here, a targeted strategy is required.

It's not just about considering technical SEO aspects in your website's source code. Equally important is a content orientation that is specifically tailored to relevant keywords. This is the only way to ensure sustainable SEO success.

As an experienced SEO specialist, I have successfully optimized the websites of small and medium-sized companies (SMEs), large corporations and institutional organizations. Let us work together to ensure that your online presence receives the attention it deserves.

I have already acquired an SEO certificate from UC Davis (Coursera).

Technical SEO

Technical SEO forms the backbone of a successful website and focuses on all on-page factors.

This means the infrastructure that runs your website - from the web server settings to graphics and other media assets to the actual source code.

Technical SEO
The basis for true success

Loading time optimization

Fast loading times improve the user experience and are rated positively by search engines.

Mobile optimization

A responsive website that works well on mobile devices is crucial for mobile rankings.

Core Web Vitals

Metrics introduced by Google that evaluate loading performance, interactivity and visual stability, including Largest Contentful Paint (LCP), First Input Delay (FID) and Cumulative Layout Shift (CLS).

URL structure

Clear and understandably structured URLs are beneficial for both users and search engines.

Internal linking

Well-thought-out internal links distribute the “link juice” and help search engines understand the page structure.

Google Search Console & Sitemaps

An essential tool for monitoring website presence in Google. Submitting an XML sitemap to Search Console helps search engines efficiently find and index all subpages of your website.

Semantics & Structured Data

The use of semantic HTML elements and structured data (schema markup) allows search engines to interpret and represent the content of a page more precisely.

Meta Data & Above the Fold

Precise meta tags and optimization of the above the fold area ensure that users are immediately offered relevant content.

Layout Shift Analysis

Monitoring and optimizing layout shifts ensures that users have a stable and consistent experience on your website.

My in-depth knowledge of front-end development and accessibility is particularly evident here. They not only allow me to optimize precisely, but also to communicate effectively with technical teams. This is crucial to ensure that all optimization measures are implemented correctly.

I use a variety of SEO tools and can explain to you exactly what steps are needed to optimize your website. Particularly important these days are the Core Web Vitals, which have a direct influence on the user experience and are considered by Google as important ranking factors.

The goal? Increased performance, which is reflected in improved rankings in the SERPs (Search Engine Result Pages).

Take the test! With Google PageSpeed Insights you can check the speed and performance of this website and see for yourself its outstanding SEO score: [](https ://

Content SEO

Content that appeals to both search engines and your target audience.

For in-depth content SEO tasks, I work closely with a network of external freelancers who specialize in various areas of content marketing and search engine optimization. This is how we ensure that every aspect of your SEO strategy is looked after by experts.

Content SEO
Content is King

Keyword optimization & research

The foundation of every successful SEO strategy. By identifying relevant keywords, content can be created that meets both the needs of users and the requirements of search engines.

High quality & unique content

Content should provide added value for the user, be well researched and unique. Search engines prefer websites that regularly publish high-quality content.

Internal and external linking

By including relevant internal links, users are taken deeper into the website, while external links to trustworthy sources underline the credibility and authority of your content.

While my primary expertise is in technical SEO, I understand how essential content SEO is to a successful online presence. An effective strategy takes into account both technical aspects and the actual content of your website.

I offer you in-depth analyzes of how your current content influences the SERP ranking and where there is potential for optimization. The focus here is on aspects such as keyword analysis, optimization of page titles and headings as well as WDF*IDF analyses.

Competitor analyzes are particularly valuable. They not only show where you stand in comparison to your competitors, but also what strengths and weaknesses your website has in terms of content. Based on this, targeted adjustments can be made to increase the visibility and relevance of your content.


I would like to share my experiences in the area of search engine optimization (SEO).

Google PageSpeed offers a quick SEO technical assessment: []( /?

You can see how well a website ranks organically in Google by its position on the Google search results page (SERP). Enter the search word (keyword), find out related keywords and analyze in which position the target page is listed. The Google Search Console offers a very comprehensive insight into which search terms your site ranks and how well.

The procedure is structured into a technical and a content analysis, as explained above in the content.

  1. For technical optimizations, the current state is analyzed and the resulting measures are developed that prioritize effective and quickly implemented optimizations.
  2. Content optimizations are implemented by another freelancer with whom I work. Keyword and competitor analysis are the focus here.

Yes, I offer tailored SEO training suitable for both corporate teams and individuals. My goal is to provide participants with both basic and advanced SEO knowledge so that they can independently improve the visibility of their websites.

In addition to Google PageSpeed and Google Search Console, I use a number of other professional tools, including Moz, Sistrix, Ahrefs, Screaming Frog, PageRanger. These help with in-depth technical analysis and summary analysis across thousands of pages.

A thorough SEO analysis begins with an examination of current website performance. I analyze the structure, the loading process of the homepage and subpages, the technical implementation and the backlink structure. Based on this, I create a detailed report that shows both strengths and potential for optimization. This report serves as a basis for future SEO measures.

SEO is a long-term process. While some technical optimizations can bring immediate improvements, it often takes several months for content optimizations and link building to produce visible results in the SERPs.

Success is measured using a combination of metrics including rankings for target keywords, organic traffic, length of site visit, and conversion rates. It's important to look not only at search engine visibility, but also at actual business results.


Optimizing a website or app for accessibility has great advantages.

Ultimately, all visitors can navigate faster and absorb and process the content more easily. 

Institutional websites, especially those in the public sector, must undergo a comprehensive accessibility evaluation to ensure compliance with the WCAG (Web Content Accessibility Guidelines) standards and even the specific national standards.

Obtaining WCAG-compliant certification is highly recommended and, in some cases, mandatory to demonstrate accessibility at the website's launch.

In addition, barrier-freedom or accessibility is also taken into account in SEO scoring.


I have a proven track record of working on projects that have successfully achieved WCAG compliance from the outset and maintained it through subsequent audits.

Additionally, I've played a pivotal role in optimizing the accessibility of an official EU website, ensuring that it met the highest standards of accessibility.

Standards: WCAG & your national standard seal

WCAG expert knowledge

Thanks to my many years of experience and continuous training, I am deeply anchored in the current WCAG standards and guidelines and ensure their consistent implementation in web projects.

WCAG compliant video player

I have complete mastery of the technical and content requirements for accessible video players. From subtitles to audio descriptions, I ensure video content is accessible to every user.

Integration of plain language "Leichter Sprache"

What's that?! I make your website speak to everyone. I integrate a 'Leichter Sprache' page, so it's clear and easy to understand, no matter your language skills.

Sign language videos

Integrating sign language videos is part of my expertise so that deaf and hard of hearing users can also enjoy a full web experience.

Technical accessibility

My skills extend to the technical implementation of barrier-free websites, from optimization for screen readers to keyboard navigation and other assistive technologies.

Accessible forms

A particular focus of my work is on the design and implementation of accessible forms. I ensure that they are intuitive, accessible and easy to use for all user groups.

Accessibility test preparation

Thanks to my support, web projects are optimally prepared for the Accessibility (BITV) test. I not only help with the implementation of the requirements, but also with successfully completing the test and achieving the coveted BITV-compliant seal.

Compliance with WCAG (Web Content Accessibility Guidelines) goes beyond mere legal obligations. It ensures that web content is accessible and user-friendly for a wide audience, enhancing reach and user experiences.

In my expertise in the realm of WCAG compliance, I've addressed specific needs, including the integration of WCAG-compliant video players. These players offer features like subtitles and audio descriptions to make videos accessible to all user groups.

I've also gained experience in crafting websites in plain language, making information understandable for those with learning difficulties or limited language skills.

Another critical aspect of my work is the integration of sign language videos, enabling deaf and hard of hearing users to access content visually, contributing to a more inclusive web presence.

With my experience and expertise, I'm here to help ensure the accessibility and inclusivity of your digital offerings.
