What I'm looking for

I’m seeking a full-time remote Senior Executive Assistant or Chief of Staff role supporting a C-suite executive or founder at a high-growth global organization. I’m available across US, UK, and global time zones and excel at proactive, confidential execution.

I’m a results-driven Senior Executive Assistant and emerging Chief of Staff with 10+ years of progressive experience supporting leaders in fast-moving, high-ambiguity environments. I thrive where discretion, prioritization, and calm coordination are essential to keeping strategy on track.

In my most recent role, I operated as de facto Chief of Staff and CEO-level support, owning the operational, communications, and administrative agenda. I protected leadership time through airtight inbox triage, complex diary and calendar management across multiple priorities, and reliable meeting and action follow-through—ensuring 100% on-time execution for senior leaders.

I’ve built scalable administrative systems from scratch—creating SOPs, filing, reporting, and procurement workflows that reduced document retrieval time by 30% and overhead expenses by 12%. I’ve also automated repetitive workflows using AI tools including ChatGPT, driving productivity improvements of up to 30% while preparing executive briefings, board packs, performance dashboards, and proposals with precision.

Earlier, I supported founders and senior managers across multi-country, multi-time-zone initiatives, preparing executive-ready documents (contracts, donor reports, budget schedules) and coordinating travel, agendas, and minutes. I also supported regional leadership across 13 African countries, handling end-to-end event logistics and confidential reporting—consistently maintaining accuracy, compliance, and stakeholder-ready communication.
