For more than 15 years I have been successfully developing software solutions for my customers in the Berlin area and beyond. Above all, websites and web applications are my main areas of work.
First and foremost is the implementation according to the interests of the client and the use of modern technologies and inexpensive solutions to optimally achieve the goals of the respective website or web application.
Ensure close communication with my customers and quick adjustments during development Results and solutions that make the respective website or web application exactly what is desired.
I also use my experience for customers from Berlin and beyond who just want advice and help with their choice need the right software solution for your requirements.
From the first idea to ongoing care — websites and web applications from a single source.
Unique, contemporary and modern websites are my main focus. I pay attention to good usability, fast loading and search engine optimisation – with CMSs such as Statamic, Concrete5 or Nera.
I bring your processes online – without expensive licences or cumbersome updates. Use it from anywhere, with top priority on data protection, data security and good usability.
For existing websites I take over maintenance, further development and content care – always up to date, technically and content-wise, including optimisation for mobile devices.
Outdated systems often carry dangerous security risks. I modernise your website affordably and reliably, so hackers find nothing to attack.
SEO, data protection, choosing a host, checking quotes: as your independent consultant I answer every question about your website openly and honestly.
A selection of websites and web applications for clients – and products of my own that I build and run.

I've been a website and web application programmer for more than 15 years. Different customers and different technologies have driven me again and again to achieve the best possible results and develop solutions. The consideration of the requirements of the respective target group and users, as well as the wishes and ideas of my customers are always the most important basis for me.
For me, quality does not contradict cost-effective solutions. I develop websites and web applications always with high demands on functionality, optimization for search engines and various end devices, no matter how high my customers' budget is.
When working with my customers, openness and honesty come first. I see me as your expert in all questions related to your website or web application and would be happy to share my expertise, even if I am not allowed to implement your project because, for example, you only want a second opinion from me for an existing offer.
For a quick response, reach me by phone or email. I look forward to hearing from you.
