About Christine

Management controller and treasurer, I support VSEs, SMEs, and freelancers in managing their financial performance and cash flow.
I primarily focus on:
– Implementing and improving monitoring dashboards (budget, treasury, cash flow)
– Financial analysis and tracking of actual vs. budget variances
– Structuring and validating Excel reports
– Aiding decision-making with clear and actionable financial indicators
I have worked in demanding environments (large corporations, finance) and now I leverage these skills for organizations needing simple, reliable, and tailored tools.
My goal: to save you time, provide visibility, and give you control over your finances, with concrete and immediately usable deliverables.
