What I'm looking for

I seek senior roles where I can drive B2B revenue growth, implement RevOps and CRM improvements, lead cross-functional teams, and scale client partnerships in a data-driven, collaborative culture.

I am an accomplished Account Director and Partnership Manager with over 15 years of experience in IT, SaaS, and agency sectors, focused on driving sustainable B2B growth through strategic client relationships and efficient revenue models. I have led cross-functional teams, transformed business models, and implemented Revenue Operations strategies using HubSpot and AI to boost sales conversion and client satisfaction.

I have driven major account wins across EMEA and APAC, secured long-term global contracts, and delivered measurable results—86% agency revenue growth, a 30% rise in sales conversions, and award-winning projects (Transform Awards 2024; REBRAND 100® Global Awards 2024). I prioritize clear communication, process automation, and data-driven decision-making to scale revenue and operational excellence.
