Back to original languageAbout Moritz
I support companies that need experienced development expertise for their Android projects on a short-term or temporary basis – to implement complex projects quickly, cleanly, and reliably.
With over 10 years of Android specialization, I develop performant, maintainable applications for smartphones, vehicles (AAOS), smartwatches (Wear OS), and VR & AR glasses (Android XR).
I combine technical excellence with human professionalism – clear in approach, clean in code, pleasant in the team.
I am employed and socially insured by Proxxler GmbH; project contracts are concluded through Proxxler GmbH.
This means all assignments are legally and organizationally fully secured – clients have no risk of bogus self-employment.
I stand for:
- Quick project start with minimal onboarding
- Pragmatic solutions and clean software architectures (Kotlin, Compose, MVVM, Clean Architecture)
- Collaborative partnership at eye level with Product & QA
- Reliability, friendliness, and team spirit as lived values
