What I'm looking for

I seek FP&A or finance systems roles where I can improve forecasting, automate reporting, and build dashboards to support data-driven management decisions.

I am a Senior Financial Analyst with extensive FP&A, consolidations, and finance systems experience across healthcare, energy, and tech sectors.

I improved forecast accuracy to 95–98% month-over-month, built real-time dashboards, and automated reporting to accelerate decision-making and efficiency.

I have supported regional and global reporting, harmonized ERP processes, reduced operational costs, and led finance controls for multi-country entities while founding a consumer brand.

I bring advanced Excel, planning/BI tool expertise and a pragmatic, results-driven approach to optimizing financial processes and delivering clear management insights.
