My name is Christian Beier. I'm a Berlin-based programmer with over 7 years of software engineering experience. I can help you with challenges in the following areas:
When developing apps for Android. I am the developer of a popular app for remote maintenance (MultiVNC for Android, 50,000+ downloads) and have brought around 20 apps to the Play Store in the course of my career so far. My particular strength in the development for Android is my experience in dealing with JNI, i.e. the connection of native C/C++ modules into Java apps.
When developing iOS apps. I am well versed in using XCode and Objective-C and have brought around 15 apps to the Apple AppStore.
For all embedded projects that have to do with OpenWrt. Here I can quickly create solutions in shell script and, if necessary, also create native binaries for all supported platforms. I am very familiar with the peculiarities of cross-compilation for OpenWrt.
When setting up continuous integration/deployment pipelines (CI/CD) for TravisCI and Gitlab.
When creating cross-platform GUI applications (Windows/MacOS/Linux) with wxWidgets/C ++.
When programming GTK+ GUI applications.
As a freelancer, I work iteratively/lean in milestones, which I develop together with you before the start of the project. Feedback from you during a project is important to me; I myself give status updates to you at least once a week.
Working together in a larger team is just as familiar to me, both as an employee and as a team lead. Here, too, I appreciate close feedback loops and agile methods such as Scrum.
Christian was fantastic to work with. His work was on-time he consistently communicated with us throughout the process. We could not ask for more, Christian is a true professional and we would be happy to work with him again.

Herr Beier programmierte für uns eine Android-App zur Benutzung im Umfeld der Marktforschung. Innerhalb sehr kurzer Zeit setzte er unsere Vorstellungen fachgerecht um und arbeitete auch nachträgliche Änderungswünsche schnell ein. Wir können ihn als Android-Entwickler weiterempfehlen.
