Du baust produktive KI-Systeme (LLM, RAG, Agenten) für große Kunden im öffentlichen Sektor. Kein Prototyp für die Schublade, sondern Software, die im Regelbetrieb läuft. Wer wir sind Rockstardevelopers, gegründet 2015, Büros in Stuttgart und München. Aus hunderten Projekten für Enterprise- und Mittelstandskunden wissen wir, wie man Software baut, die im Ernstfall trägt.
