Summary
🤩
RockstarHannes Achleitner is a Munich-based software engineer with 11 years of experience specializing in Android, Kotlin, Java and backend integrations.

Hannes focuses on code quality: refactors, lint fixes, lifecycle bug fixes, and migrations to AndroidX and modern Gradle, which shows a strong attention to long-term maintainability.

An interesting detail: beyond feature work he repeatedly targets build and compatibility upgrades, quietly reducing tech debt across multiple ecosystems.
