What I'm looking for

I’m looking for a customer-centric role where I can own revenue growth through consultative sales, strong account relationships, and CRM-driven pipeline management—while leveraging data insights from multi-channel marketing to improve ROI.

I’m a results-driven Sales & Customer Success professional with 10+ years of experience across hospitality, B2B sales, customer service, and digital marketing. I build strong client relationships, manage CRM pipelines, and drive revenue growth in fast-paced, customer-centric environments.

In my current role as a Sales Manager, I acquire and manage business sales transactions in the e-commerce sector and act as a key interface between sales, business valuation, and the buyer network. I focus on building and nurturing long-term relationships with both prospective and existing clients.

Previously, I planned, executed, and optimized multi-channel digital advertising campaigns, using campaign KPI analysis to implement data-driven improvements that maximize ROI. Earlier experience also includes customer service with complex insurance claim resolution and sponsorship sales with accurate CRM pipeline reporting—along with a strong hospitality foundation from guest-facing roles through hotel management training.
