What I'm looking for

I seek a senior customer success role where I can scale programs, apply AI-driven insights, lead cross-functional teams, and drive retention and expansion in a collaborative, data-driven company.

I am an AI-driven customer success leader with seven years scaling customer success programs in high-growth, high-stakes environments. I combine technical fluency in BI and AI tools with strategic leadership to drive retention, expansion, and measurable adoption gains.

I have directed portfolios worth $25M+ ARR, achieved 115% NRR and 97% GRR, and led cross-functional initiatives that improved adoption by 18% and forecasting accuracy by 30%. I build playbooks, standardize operations, mentor teams with zero attrition during scaling, and serve as a trusted advisor on responsible AI adoption.
