Skills

Hi, I'm Maximilian and Freelance Android Developer (Java + Kotlin) coming from Berlin. I have more than 8 years experience in developing high-quality and performant apps. Further I graduated from TU Berlin with a Bachelor's degree in Business Informatics.

I support my clients with their Android projects. Besides high-quality, well-documented and secure code, I pay close attention to good design. Because: Every great app needs next to a performant and modern code base, a user-friendly design.

Honesty, reliability and a team player mentality are the foundation of my work. I like to work in teams as well as on my own. When working in a team I highly value a great communication and I inform my clients at all stages of the project.

In my free time I like to work out, cook and spend time with my family and friends.
