What I'm looking for

I’m available for fixed-term or full-time remote engagements and I’m looking to support senior leadership in fast-paced, high-growth environments—owning executive calendars, cross-timezone scheduling, travel coordination, inbox gatekeeping, and discreet communication.

I’m a proactive, highly organized Executive Assistant with 10+ years of experience supporting senior leadership in fast-paced, high-volume environments. I manage complex executive calendars, act as a trusted gatekeeper, and handle competing priorities with strong judgment and the highest discretion.

I coordinate multi-timezone scheduling and stakeholder communications in English and Spanish, ensuring seamless day-to-day operations. I also arrange intricate travel logistics and itinerary planning, and I prepare briefing documents, reports, and executive correspondence ahead of key meetings.

Beyond core executive support, I’ve managed administrative operations in a Fortune 500 setting and served as an interim Team Manager across multiple projects. I’m experienced with organizational record maintenance, workforce scheduling (WFM), back-office operations, and escalation handling, using tools like Microsoft Office, Google Workspace, Asana, Zoom, and AI productivity tools.
