About
Dear Hiring Manager, I am writing to express my interest in the Virtual Assistant position within your team. With over 11 years of experience in the construction industry and a strong background in administration, document preparation, and project coordination, I am confident in my ability to bring organization, reliability, and initiative to your remote operations. In my previous roles, I have managed day-to-day administrative functions including managing email correspondence, scheduling meetings, preparing detailed reports, and maintaining project documentation. I am proficient with Microsoft Office, Excel, cloud storage platforms, and industry-specific tools such as PlanSwift, and I am quick to learn new systems including CRM and project management software. I understand the importance of attention to detail, timely communication, and self-management in a virtual work environment. My experience in coordinating construction schedules, managing subcontractor communications, and handling cost and contract documentation has helped develop my ability to multitask and remain efficient even under pressure. I am excited about the opportunity to support your team and help streamline daily workflows. I am available to start immediately and would welcome the chance to further discuss how I can contribute to your business. Thank you for your time and consideration. Sincerely, Ma. Catherine Cabreros Toos
