Description

Ich bin ein Senior iOS Entwickler mit über 8 Jahren Erfahrung. Ich habe an der Kaufland App für die Schwarz Gruppe gearbeitet, interne Apps für STRABAG AG entwickelt und die STRAFFR Fitness App fast komplett selbst gebaut. Bei Finarx GmbH habe ich an iOS‑ und Flutter‑Projekten gearbeitet. Früher war ich iOS Security Researcher bei Fraunhofer während meines Masterstudiums in Frankfurt.

Ich arbeite zuverlässig, schreibe sauberen Code und unterstütze Teams bei neuen Features oder ganzen Apps.

Meine Arbeitssprache ist Englisch. Ich spreche nur ein bisschen Deutsch (A2).
