Description

Hi, I'm Max, a freelance Senior Android Developer.

With over 17 years of experience in software development and specifically 13 years in Android app development, I bring a wealth of expertise and practical experience. I hold a Bachelor's degree in Business Informatics from TU Berlin and can provide a variety of references from satisfied clients – ranging from start-ups and medium-sized companies to large corporations.

I would be happy to support you in the conception and development of your projects. In addition to high-quality, tested, and secure code, I always place great emphasis on modern architecture, design, and communication. Through my many years of experience, I have already worked in various teams and company sizes. I strive to incorporate the knowledge gained from this into all my projects to the best of my ability.

‍

Honesty, reliability, and a team player mentality are a matter of course for me at all times. I enjoy working in a team, or alone. In team projects, it is important to me to strive for good communication with every team member so that the project can be carried out in the best possible way. I would describe myself as a very open person. In my free time, I do sports and enjoy cooking.
