who i am
Hey there, pleasure to meet you.
I am Dennis, a full stack developer located in Berlin.
Creating websites and web apps has become part of my DNA, and I couldn't live without it.
In my free time I enjoy rowing, playing badminton and riding the bike. I also enjoy the occasional motorbike tour or a good movie.
And yes, that all fits together somehow :)
what i do
think
I really enjoy finding solutions to challenging problems. Complex situations motivate me as well as finding the best possible solution, whether it is by creating user-friendly interaction possibilities or by testing and optimizing the site or app to maximize revenue.
talk
Acting solution-oriented is one of my biggest strengths.
Good at keeping track of multiple projects at once, I will make sure that
each task is taken care of, even if a problem is not within my responsibility.
build
As soon as the goals for the project have been defined sufficiently, I am all in for delivering fast, testable and understandable code that will satisfy the users requirements and detect and deal with issues not visible prior to development.
Ehmm great, but what does that mean for me?
Sorry, didn't mean to be airy. What I can do for you is:
- Develop an excellent website or web app as a full stack developer based on over 10 years of professional experience
- Be an active participant in meetings and requirements engineering, understanding your needs due to my previous work as product owner and scrum master
- Communicate professionally with you and your customers, as I did as a freelancer in the last 14 years
