What I'm looking for

I seek a role combining Salesforce administration, payroll or customer-facing operations where I can apply technical skills, deliver accurate processes, and grow into broader administrative leadership.

I am a Marine Engineering graduate from the Technological Institute of the Philippines with hands-on experience in customer service, payroll processing, and Salesforce administration.

I have delivered timely results in high-volume support roles at Concentrix/Amazon and TaskUs, managing customer inquiries, order fulfillment, and complaint resolution while maintaining professionalism under pressure.

Most recently I worked as a Payroll Specialist and Senior Salesforce Administrator, where I processed payroll, handled tax and year-end tasks (W-2/1099), and supported customers on payroll-related matters using Salesforce and DocuSign.

I combine technical knowledge of HVAC systems with strong administrative skills, CRM management, and a customer-focused mindset to ensure accurate operations and excellent client experiences.
