I am a Christian with Reformed theological convictions. This means that I recognise that I am a great sinner, but Jesus Christ is an even greater saviour.
Given that my relationship with Christ is the foundation of my identity, everything else I might tell you about myself is relatively unimportant. However, here are a few other things you might be interested to know.
I was born to Rebecca and Paul Demchick, two microbiologists. I grew up with a great number of advantages due to their careful parentage. My father began teaching me rudimentary computer programming when I was around 6 years of age; this has since become the cornerstone of my career.
I live in Aotearoa New Zealand. I have studied the Maori language, the original language of New Zealand, and am moderately competent with it. At the moment, I live and work in Palmerston North
My vocation is in IT. I have experience as a system administrator, database administrator, and software engineer. My skillset is outlined below, should you be interested.
Though I fail continously, my ideal is to live according to the teachings of the Bible. In summary, this means I am to love God with all my heart, soul, and mind, confessing Him as Lord. I am also to love my neighbour as myself.
One important application of this is in business, where I am to see myself as working for Jesus whenever I work for a client.
I subscribe to the SQLite Code of Ethics
