I am passionate about writing software that solves problems and saves time.


I am a programmer who loves his job. But more than this, I am a person who wants to help others – with well-designed applications. I am passionate about writing software that solves problems and saves time. The most important thing to me is not the number of billable hours, but the number of saved working hours.


For me, a project succeeds if the people really want to work with my software. The key to this is communication. Therefore, close communication with the people who are going to work with the new piece of software is essential to me. In this way, I can ensure that every application really fits the needs of my clients and will pay for itself in a very short period of time.

Oracle APEX Expert - IT Consultant


There are two things which principally drive me: solving problems and finishing projects. In my opinion, the first one is innate to every programmer, because creating software is all about solving problems. The ability and motivation to bring a project to completion is one of my USPs.


Nowadays, demands for an application are rapidly changing. For this reason, I focus on the long-term viability of your software throughout the whole development process. I will also be your brainstorming partner and will come up with many examples and best practices to ensure that your application is ready for the future.
