About Sihem

Administrative Assistant / administrative with solid experience in a B2B environment, I support SMEs and startups in managing their day-to-day back-office.
Autonomous, organized, and reliable, I intervene in tasks related to order tracking, invoicing, administrative management, data updates, and written customer support.
Accustomed to working remotely, I quickly adapt to existing tools and processes (ERP, CRM, Excel, collaborative tools). My goal: to save you time by taking charge of operational tasks with rigor and efficiency.
Available a few hours a week, I prefer simple, fluid, and lasting collaborations.
