What I'm looking for

I'm looking to support founders, CEOs, or executive teams by owning administrative operations, improving workflows, automating repetitive work, and building dependable systems that help teams move faster.

I've supported CEOs, founders, and executives at Grosvenor Constructium Ltd, Madison Avenue Entertainment Group, and through freelance client work. I manage calendars, inboxes, stakeholder communication, CRM records, project coordination, and decision-ready reporting with discretion and ownership.

At Grosvenor Constructium, I reduced scheduling conflicts by 22%, improved document retrieval time by 35%, and built a compliance documentation system that achieved zero submission errors. I also improved HubSpot data accuracy and follow-up efficiency by 12% while coordinating meetings across time zones with 100% on-time execution.

I build practical systems that last: workflow automations in Make.com, N8N, and Zapier; SOPs and process maps; and structured inbox, calendar, and priority-reporting workflows for C-suite clients.
