Let me introduce myself first. I used to be a Textile Chemist graduated from Hong Kong Polytechnic. And I have a disruptive journey in my career in the last 40 years. Now I am the Chief Technical Officer of a startup and the Regional Quality Manager of a Fortune 100+ Technology Platform company with Asia Headquarters in Hong Kong Science and Technology Park. I hold a patent in a device related to Internet of Things. Glad to join this online course as a transition to my retirement plan.
