What I'm looking for

Ich suche flexible kaufmännische oder projektunterstützende Rollen (70–100%), in denen ich Prozesse, Stammdatenpflege und Office-Organisation mit SAP/Collaboration-Tools weiter ausbauen kann.

Ich bin eine erfahrene kaufmännische Assistentin und Sachbearbeiterin mit Schwerpunkt Projektunterstützung, Büroorganisation und Datenmanagement. Über viele Jahre habe ich in unterschiedlichen Branchen gearbeitet, von Energie- und Finanzdienstleistungen bis zu öffentlichen Einrichtungen.

Meine Stärken liegen in der Rechnungsprüfung, Zahlungsverkehrsprozessen, Sachbearbeitung und dem Umgang mit SAP, Navision sowie diversen Office- und Kollaborationstools. Ich übernehme gern Verantwortung für On-/Offboarding, Stammdatenpflege und Prozessunterstützung.

Ich habe wiederholt Team- und Projektassistenzfunktionen ausgefüllt, Veranstaltungen und Meetings organisiert sowie als Single Point of Contact für SharePoint und andere Plattformen gearbeitet. Technisch versiert unterstütze ich First-Level-Support-Aufgaben und die Nutzung von Tools wie Jira, ServiceNow und f4.

Ich suche flexible Einsätze (70–100% Auslastung) und bringe sofortige Verfügbarkeit sowie Mobilität innerhalb Deutschlands mit. Zertifizierungen wie ITIL Foundation, PSM I und PRINCE2 unterstreichen meine Projekt- und IT-Affinität.
