About Sebastian

For over 14 years now, I have been working as a self-employed app developer. During this time, I focused 100% on the Android platform until the end of 2018 to become an expert in this field.

In 2018, I first heard about Flutter, Google's “Portable UI Toolkit”, and developed a great fascination for it. With Flutter, the development of native and high-quality apps with higher developer productivity in a short time, simultaneously for Android & iOS, becomes a reality. This is the first technology that has been able to convince me of the cross-platform development approach. I am sure that Flutter is the best choice for most app projects and would now like to help companies implement their apps with Flutter.

When developing apps, I attach great importance to a well-maintainable and testable architecture. I also see code reviews as another way to achieve good code quality, which I also like to encourage teams to do.

Due to my independent way of working and my experience, I can take on projects and tasks independently. Likewise, I integrate very well into teams to support them.
