King Ho

Support Engineer
IT at Greenpeace isn't your average desktop support job. I have learnt to be extremely flexible with the application of technical knowledge and experience to a variety of, sometimes not so IT-related, tasks. From projection-mapping to solar-array design, the IT team in GPI tries to push the boundaries of a traditional support role to a more pro-active facilitation one.
