About Sami

Working at the heart of challenging and fast-growing environments, I support executives and startups in structuring and managing their daily operations.
My daily routine? Moving from one subject to another with agility and rigor to secure your operations.

Specializing in supporting startups, I take care of all your support functions by combining operational expertise and the ability to implement clear processes to structure your back office.

My areas of action are organized around 6 major pillars:
  • Procurement Management (from collecting accounting documents to paying suppliers)
  • Sales Administration (from customer invoicing to debt collection monitoring)
  • Bank Account Management (monitoring bank balances during the month based on upcoming deadlines, performing inter-account transfers, managing foreign currencies, and optimizing bank fees)
  • Payroll Management (administrative monitoring of employee onboarding/offboarding and management of the internal payroll tool, from collecting payroll variables to payroll closing)
  • Physical and Electronic Mail Management (delegated management of email inbox / reception, processing or distribution to the relevant people)
  • Pre-accounting (bank reconciliation and analytical accounting categorization of expenses and revenues to facilitate accounting processing by the dedicated team)
Tools & Software mastered: Pennylane, Payfit, Google Suite, Spendesk, Qonto (quick mastery of any new tool).

Why work together? Accustomed to working under pressure and in fast-paced ecosystems, I stand out for my responsiveness, my rigor, and excellent interpersonal skills (essential for interacting with your clients, suppliers, and teams).

Let's discuss your current challenges to structure your operations and free up your time!
