What I'm looking for

I’m looking for a remote, metrics-driven customer support role where I can own escalations, resolve billing/payment issues, and use Zendesk/Salesforce to improve CSAT, first-contact resolution, and SLA compliance through empathy and process improvement.

I’m a Senior Customer Service Representative with 5+ years of remote experience delivering high-volume support across chat, email, and phone channels. I’m known for empathetic communication, structured problem-solving, and genuine ownership of every customer interaction.

I consistently deliver results, including a 95% CSAT score, 99% first-contact resolution rate, and a 22% reduction in escalations. I handle billing and payment disputes with Stripe and PayPal, maintain SLA compliance, and lead root-cause analysis to prevent repeat issues.

Across Zendesk and Salesforce, I keep audit-ready, seamless documentation and ensure smooth handoffs across shifts and time zones. I also redesign support workflows to reduce errors and improve verification and enrollment accuracy—while staying focused on clear, jargon-free guidance for customers and strong follow-through.
