What I'm looking for

I'm seeking a customer-focused role where I can apply CRM and billing expertise, improve collections, coach teams, and work in a collaborative, growth-oriented environment (remote or hybrid).

I am a customer service professional with over five years of experience delivering high-quality support in both remote and in-person settings. I focus on resolving issues quickly while maintaining strong client relationships and driving repeat business.

I have a proven track record—achieving 94% on-time payments, reducing aging accounts by 25%, processing 500+ invoices monthly, and maintaining an 85% issue resolution rate. I also trained new team members and implemented efficiency improvements using Salesforce, Zendesk, and Microsoft Dynamics.

I prioritize clear communication, efficient problem-solving, and dependable follow-through. I bring expertise in billing, collections, CRM management, and remote collaboration tools to improve customer satisfaction and operational performance.
