What I'm looking for

I’m looking for a B2B role where I own the full client lifecycle—pipeline, deal execution, and retention—using CRM discipline, clear communication, and process improvement in a fast-paced yet well-structured environment.

I’m a business and client relations professional with 7+ years of experience spanning sales, account management, operational coordination, and communications. I’ve owned the full client lifecycle—from prospecting and qualification to closing, onboarding, and long-term relationship management—while staying a reliable point of contact across multiple stakeholders.

I consistently deliver above expectations in both fast-paced sales and structured operational support. As an Account Executive at Vonage Business, I managed the full sales cycle for UCaaS, consistently exceeding MRR quota of $5,000/month and averaging $6,000–$7,000 MRR across deals. I also supported junior team members by reviewing their work and coaching them on client communication, qualification, and pipeline management.

In client-facing operational roles, I combine negotiation, issue resolution, and workflow improvement to keep every step moving smoothly. As an Account Manager, I served as primary point of contact for 5 B2B international trade accounts, managing end-to-end order execution and closing transactions up to $28,000—including the company’s single largest deal. Most recently, I managed outbound prospecting and operational workflows in HubSpot and refined outreach templates while working independently with minimal oversight.
