After 10 years leading the UK, I am now in a global role focused on two areas: one leading a people project, the other focused on marketing.

'Continuing to "enjoy" life'
My lifelong mission is to continue positively influencing both myself and those around me, while persistently seeking enjoyment.
Throughout my career, I've had various experiences, from utilizing cutting-edge technology in logistics to engaging in gritty tasks. Through these experiences, I've realized the importance of finding meaning and joy in everything I do. Although sustaining this mindset is not easy, I am committed to continuous learning to become a professional to bring a positive impact to people and organisations.
