What I'm looking for

I'm looking to grow client accounts and lead data-driven marketing strategy, retention, onboarding, and multi-channel campaign execution, ideally in a remote-friendly role.

I've grown managed client portfolios at Relentless Digital from $12.7K to $76.3K in monthly recurring revenue, independently managing nearly 30 accounts totaling more than $916K in annualized recurring revenue. I combine proactive value consulting, account health reviews, onboarding, and multi-service packaging to expand accounts and reduce churn.

At AKA NYC, I led Google Ads campaign alignment for organizations including The Metropolitan Museum of Art, YMCA of Greater New York, and NYBG, translating analytics into strategic performance insights for clients and cross-functional teams.

I've also led marketing operations for a top-ranked real estate group and provide freelance client success consulting across Google Ads, Bing, and Merchant Center. I use HubSpot, ClickUp, Asana, Slack, and AI tools to build efficient workflows, improve campaign ROI, and support long-term client growth.
