What I'm looking for

I’m looking to lead customer success and channel growth in SaaS, aligning technical and commercial teams to improve retention, expand revenue, and scale partner operations—using automation and AI to boost efficiency and customer experience.

I’m a Customer Success and Channel/Partner growth professional with over 10 years of experience in SaaS and ERP ecosystems. I specialize in connecting technical, commercial, and marketing teams to drive revenue growth, improve customer retention, and scale partner channels through strong communication and hands-on execution.

In recent roles, I’ve led partner development and performance—supporting sales strategies, negotiations, deal closing, and objection handling—while delivering operational process optimization. I focus on churn reduction, scalable workflows and automations, and the application of AI to improve operational efficiency and customer experience, ensuring partners and customers get consistent, high-quality outcomes.
