Johnry Eusebio Sinaguinan

I am a detail-oriented and highly reliable Executive Assistant and Administrative Operations Specialist with over 9 years of experience supporting C-level executives, attorneys, and business leaders across the U.S., Middle East, and Southeast Asia. Throughout my career, I have delivered proactive administrative support in high-pressure environments, ensuring operations remain organized, efficient, and aligned with executive priorities.

My background spans industries such as construction, real estate, legal, and corporate administration, with a proven track record of managing executive calendars, facilitating communication across teams, and handling confidential documents with precision. In my most recent role as Legal Assistant for a U.S.-based law firm, I supported attorneys by preparing legal documents, coordinating hearings and depositions, managing case files, and communicating with clients and medical providers—ensuring cases progressed on time and with accuracy.

Previously, I worked remotely for a California-based roofing company, where I managed executive schedules, handled invoice processing using QuickBooks, and maintained vendor and CRM records. My experience also includes supporting high-level executives in Saudi Arabia, where I assisted in procurement and bidding operations while managing payroll and documentation compliance. Each role has refined my ability to anticipate needs, communicate clearly, and execute under tight deadlines.

I am technically proficient in platforms such as Google Workspace, Microsoft Office, HubSpot, QuickBooks, ClickUp, Notion, SAP, Oracle, and Zendesk. My skills in CRM management, email handling, legal documentation, and administrative coordination help executives and legal professionals stay focused on strategic decision-making while I manage the day-to-day operational details.

I hold a Bachelor of Science in Hotel and Restaurant Management from the Polytechnic University of the Philippines, and certifications in Lean Six Sigma (Yellow and White Belt), which I use to continually improve workflows and reduce inefficiencies.

I thrive in fast-paced, remote work environments and pride myself on my ability to maintain professionalism, discretion, and structure. Whether it's preparing case files, scheduling board meetings, or liaising with clients, I take ownership of each task and ensure high standards are met. My goal is simple: to be the behind-the-scenes force that keeps leaders organized, informed, and free to focus on what matters most—strategy, growth, and impact.
