At IT Profis, I develop Android applications for fintech solutions, POS devices, and digital signature platforms. I work with Kotlin, Jetpack Compose, and workflows involving PDF handling, biometric authentication, and secure document signing.
At Anacafé, I developed and maintained native Android applications using Kotlin and Java with MVVM architecture, and built cross-platform applications using React Native and Flutter. I also supported web development with React and PHP and handled publishing and support for Google Play and the Apple App Store.
At Research Mobile, I developed Android applications and contributed to planning, testing, feature reviews, and production releases. My work included REST API integration, local data persistence, and Flutter projects for applications such as inventory systems and credit card delivery apps.
