What I'm looking for

I’m seeking a customer-focused role where I can lead teams, resolve complex queries, use Salesforce/NetSuite, improve processes, and grow within a collaborative, service-driven company.

I am an experienced and reliable customer service professional with over 10 years in retail, hospitality, and office environments, skilled at handling high volumes of customer interactions and resolving complaints with diplomacy.

I work daily with CRM systems including Salesforce and NetSuite, managing up to 100 enquiries per day, processing orders and returns, supporting escalations, and providing administrative support to management.

I have led and trained teams, managed full restaurant operations and large events of 150+ guests, and I bring strong organisation, proactive problem-solving, and a passion for delivering excellent service.
