Android Developer

Android-Entwickler, der seit 2018 entwickelt. Derzeit arbeitet er an einer App für eine Krankenkasse. Dafür hat er auch an einer unternehmensinternen Lifestyle-App gearbeitet, in der verschiedene Herausforderungen zwischen Teams und Einzelpersonen erstellt wurden. Über eine API holten sie sich Daten von Google Fit und zeichneten sie in ihrer internen App auf. Er arbeitet hauptsächlich in Kotlin, in Java entwickelt er nach eigenen Angaben eher Legacy-Apps. Er hat auch Erfahrung mit RXJava, MVI-Architektur, Jetpack, Coroutines. Er interessiert sich für die Arbeit mit Datenbanken, damit die Nutzer der App nicht ständig mit dem Internet verbunden sein müssen. Er hat in seiner Diplomarbeit an einem ähnlichen Thema gearbeitet und würde dies gerne weiterverfolgen, wenn er die Möglichkeit dazu hat. Er hat Erfahrung mit agilen Methoden wie Scrum und Kanban. Die Kommunikation in englischer Sprache stellt für ihn kein Problem dar. Er hatte auch schon die Gelegenheit, jüngere Entwickler auszubilden.
