What I'm looking for

I’m looking for a senior Customer Success, Customer Experience or Transformation role in an international, remote-friendly environment. I want to combine strategic customer leadership with operational improvement, take ownership of complex challenges and create measurable impact. I’m particularly open to opportunities in Southeast Asia.

I’m a senior Customer Success and Transformation leader with 20+ years of international B2B experience, including six years managing global key accounts such as Apple, Sony and Hewlett-Packard. I combine a strong customer focus with expertise in operational excellence, change management and process improvement. Having worked across countries, cultures and complex organizations—and built businesses myself—I bring both strategic perspective and a hands-on, entrepreneurial approach. I’m particularly motivated by turning customer challenges into sustainable improvements, stronger relationships and business growth.
