Turning static financial data into real-time insight

Accounting Finance Management Control Administration

With over ten years of experience, from large corporations to start-ups and small businesses, I structure the accounting and finance functions of the organizations I work with: rolling out the right tools, making data reliable, and upskilling the teams who run it day to day.

My guiding thread: giving leaders a clear, up-to-date view of their performance, rather than a snapshot taken several weeks late — through data that is reliable, structured and available on an ongoing basis.

This expertise was built across very different assignments — accounting firm, hospitality, crowdfunding, energy, healthcare — which taught me to adapt quickly without ever compromising on rigor or compliance. The full detail of this background is below.
