What I'm looking for

I’m looking to own end-to-end FP&A and financial controlling, build scalable reporting and billing workflows, and improve cash flow visibility—partnering closely with stakeholders. I want a role where AI supports daily forecasting, variance analysis, and decision-making.

I’m a finance professional with 15+ years of experience in FP&A, financial controlling, and process improvement. I’ve built and implemented automation that turns complex operational data into actionable decisions, especially across multinational and e-commerce environments.

In my JLL roles, I replaced budget-based models with end-to-end financial infrastructure, owning budgeting, variance analysis, and billing visibility at EMEA scale ($50M+ portfolio, 20 countries, 9 currencies). I also built automated reporting systems from scratch (including Google Sheets dashboards) and delivered a 5-year retroactive cash reconciliation across 2,000+ SKUs—covering inventory FP&A, COGS analysis, and OPEX monitoring.

My instinct is to push past the “what” toward the “why,” and I use AI as a working partner—already embedded in my daily workflows for reporting automation, variance analysis, and forecasting across 20 EU countries. I bring a high-accountability, collaborative style, and I enjoy leading finance processes end-to-end: from reconciliation and cost control to forecasting and stakeholder-aligned improvements.
