About

Commercial and execution leader with experience across Sales, Operations, and Customer Success in technical B2B environments. I’ve led revenue portfolios, managed and coached sales teams, owned enterprise client relationships, and run delivery operations across multiple countries. My background includes full-cycle sales, account ownership, onboarding and adoption, forecasting, and cross-functional execution with senior stakeholders. I’m strongest in roles where growth, execution, and customer outcomes need to stay aligned, particularly in fast-growing or scaling organizations.
