About Ya Shi Tan

My collective 15 years as a marketing professional has ridden through exciting milestones; most of which I’m grateful to have pioneered. From the most recent organisational and digital transformation at M1, to fuelling the start of a digital era with developing and launching the Prepaid Mobile App and portal, launching NFC as well as transformed the way Sony earphones were marketed as a wearable fashion accessory.This breadth of accomplishments completes the depth of my experience in leading the team that looks after churn and customer lifecycle management of telco customers. As a keen practitioner of data driven activities, I am passionate about insights from big data, market trends and consumer feedback.The one accomplishment I am most pleased is to consistently deliver despite constraints in resources. In the face of adversity, keeping calm and being creative has always helped me to find a work around challenging situations.My cheerful, positive and authentic disposition shines through my management and work style; cultivated from more than a decade of teaching young kids at children’s ministry at church.
