What I do


Those who want to be successful today need a professional website. Just as important for success is that the websites are found. From consulting and conception to search engine optimization, I work hand in hand with my customers to develop optimal digital communication.

Consulting & conception

Everything from a single source: From the first idea and vision to the finished concept. In close cooperation with my customers, I develop tailor-made solutions and strategies for a successful website. Reliable and transparent.

Implementation & operation

Layout and technical architecture are implemented in constant exchange with my customers. I ensure that the website runs smoothly and continuously develop the systems together with the customers.

Search engine optimization

The decisive factor for success is that the website can also be found on Google & Co. Search engine optimization strategies are already taken into account when designing the website. My years of experience and my extensive know-how in this area ensure a top position in Internet searches.

Individual software

In addition to professional websites, I also develop apps and software, individually and tailored to the business model of my customers. When it comes to technology, I rely on "state of the art" in order to successfully implement the projects. A transparent and reliable calculation ensures planning security.

Frontend development
When realizing graphical user interfaces for web software and apps, I take into account the specifics of different target groups for a high level of user experience. Of course, using modern technologies.
Backend development

The invisible part of software - such as database operations, complex business logic or security mechanisms - I implement in one go and precisely tailored to the wishes of my customers. I attach great importance to the security and stability of software.

Service integration

I integrate my customers' peripheral systems into new and existing software solutions and fully integrate them. Whether sending mail, cloud native services or the integration of payment providers. I am fluent in important programming languages, so that I can communicate with third-party systems and interfaces on an equal footing.

Diverse customers

Website for artists

Comedy and magic

Rudi Lauer is the cozy, personable Saarlander from next door, who is not so easily disturbed and who almost becomes a little nostalgic when he compares earlier times with today.

Search engine optimization

1st place on Google

My strategy for search engine optimization was successfully implemented at the video marketing agency Onpräs. The Onpräs website positions itself organically in the Google search with relevant terms among the top hits and usually takes first place.

Individual Software

Film music archive

The software for a complex music archive was developed together with the renowned commissioned composer Sergios Roth. Film, TV or advertising professionals will find an abundance of songs specially composed for film use, which can be compiled and used for film or TV productions.

Custom-fit solution


A modern online magazine was developed and successfully implemented together with the customer: With around 2 million page views per year, Getränke News has developed into a leading news portal for the beverage industry since it was launched in October 2018.

I about myself

"More than zeros and ones"
