What I'm looking for

I’m looking for administrative, coordination, and operations support roles where reliability matters. I want to own details, keep records accurate, and support fast, CRM-driven case resolution across cross-functional teams.

I’m a detail-oriented Collections & Billing professional who keeps people, processes, and information organized to drive reliable outcomes. I currently work as a Billing & Collection Specialist, managing documentation, case tracking, and accounts receivable for 150+ healthcare partner accounts, with a focus on payment discrepancies, invoice tracking, and accurate financial records. In my role, I’ve maintained over 95% accuracy in accounts receivable and resolved billing disputes with clarity and empathy while collaborating across teams to streamline issue resolution.

Earlier in my career, I served as a liaison in hospitality—logging and tracking operational issues to meet tight deadlines—and supported high-volume customer and sales environments where accuracy and communication mattered. I’m proficient in Microsoft Outlook, Word, Excel, and Teams, along with Google Workspace and various CRM platforms, and I manage calendars, records, and competing priorities without losing precision. I’m currently open to administrative, coordination, and operations support roles where consistency and ownership of details make a real difference, and I’m completing my BSc in Information Technology to strengthen how I think about systems and workflows.
