The person behind the process

I'm an Executive Assistant and Operations Manager based in London with a track record supporting C-suite executives in fast-paced, high-pressure environments — from proprietary trading firms to one of the world's leading quantitative hedge funds.

Most recently I've been supporting a proprietary trading company across diary management, bookkeeping, compliance, and recruitment. Before that, I spent nearly three years as EA to the COO and Office Manager of Europe at AlphaGrep UK — where I helped open new offices in Amsterdam and Paris, managed multi-site operations, and was trusted with sensitive financial and personnel data at the highest level.

I'm also a London Marathon finisher — which tells you everything you need to know about how I approach a challenge.
