Customer Service Representative delivering exceptional support and resolving issues for international customers.
What I'm looking for
I’m a Customer Service Representative with over five years of combined customer service and sales experience, supporting international customers in both remote and on-site environments. I focus on delivering exceptional customer experiences through clear communication, calm problem-solving, and reliable follow-through.
In my recent roles, I supported customers with billing, account management, plan changes, and technical support, while maintaining high satisfaction levels and documenting interactions in Sibelius CRM. I also handled reservations, flight changes, cancellations, and travel inquiries, using Sabre and airline tools like JetBlue Internal Operations Dashboard and BlueBook to resolve issues in line with airline policies.
I complement customer service with strong sales and administrative experience—from assisting customers with spare parts selection and processing transactions to handling delivery updates and order support. I bring organized communication using tools like Cisco Finesse, Slack, Microsoft Outlook, and Google Workspace, along with a commitment to accurate records and effective teamwork.
