Project Assistant

About

I am an operations and executive support professional with over 8 years of experience leading teams, optimizing workflows, and supporting senior leaders in fast-paced global environments.

My career has been built at the intersection of people, process, and performance. I have led teams of up to 20+ associates, managed remote executive support operations for U.S.-based leaders, and built systems that improve productivity, communication, and operational efficiency.

Currently, I focus on operations leadership and executive support, where I help organizations streamline processes, coordinate cross-functional work, and maintain operational alignment across distributed teams. I enjoy building structured systems, clear documentation, and scalable workflows that help teams perform at their best.

Some highlights from my experience include:

Leading and mentoring remote teams of Executive Assistants supporting global executives
Designing SOPs and operational workflows that improve efficiency and consistency
Managing calendars, communication, and project coordination for senior leadership
Building dashboards, reports, and trackers that support data-driven decision making
Implementing process improvements that increased efficiency by 30%

I am particularly interested in opportunities in Operations, Executive Support, Program Coordination, and Remote Team Leadership where I can contribute to building organized, high-performing teams.

Tools I frequently use include Google Workspace, Microsoft 365, Notion, Asana, Trello, Slack, and operational reporting systems.

I’m always open to connecting with professionals working in operations, remote work, and leadership support.
