About

Professional summary

I am a proactive Executive Assistant and business support professional with more than 15 years of experience in administration, client services, operational coordination, and business ownership.

I have supported directors and remote teams in UK tax, legal, HR, and international business environments. My work includes inbox and diary management, meeting coordination, client communication, documentation, records management, and workflow tracking.

I am experienced in handling confidential information with discretion and sound judgement. I enjoy anticipating needs, prioritising competing tasks, following up on actions, and keeping day-to-day operations organised.

In my recent UK tax practice role, I provided executive and operations support, coordinated client records and compliance activities, communicated with HMRC, and supported Making Tax Digital onboarding for more than 300 clients.

I am comfortable working independently in fully remote environments and collaborating through Microsoft 365, Google Workspace, Teams, Asana, GoHighLevel, Zoom, and CRM platforms. I am available to work fixed hours aligned with UK business hours, or part time aligned with US business hours.
