About Mak:

I am a mechanical engineer with long experience on MEP engineering for mission critical facilities in the Asia region, including Singapore, Malaysia, Hong Kong, Japan, China and other SouthEast Asia countries. I have spent years in managing critical facilities projects, with various and diverse focuses on the area of planning, designing, building, and commissioning. My project portfolios range from small to large scale, from data centers for banks, telcom, and colo providers, to other projects such as railway, substations, residential and commercial buildings. My latest challenge is as the regional engineer for APAC with CenturyLink Technology Solution, shifting my focus from running new build projects to operation of data centers. My professional interests include green technologies, sustainable eco-design and renewable energy. I am a LEED AP (BD+C), associate of ASHRAE, and member of the Institution of Engineers Singapore. I am working towards becoming a chartered engineer and certified energy manager. In my spare time I like reading, movies, Japanese folk music and hitting out the gym. The latest book I read is The God Delusion by Richard Dawkins. My all-time favorite movie is Leon the Professional.
