I'm a


I was born and raised in South Africa. I married my soul mate Martin Coetzee and we have two beautiful children. We love nature, exploring, hiking and camping. We immigrated to Australia in 2018 and are very proud to be associated with this beautiful country. We currently hold Permanent residence status as a family and we are commited to apply for citizenship in due course. Since moving to Queensland in 2022, we've been thoroughly enjoying everything this beautiful state has to offer.

After spending several years in the software industry and working in various customer service positions, I was presented with an opportunity to transition into software development. It was during this time that I discovered my true calling and realized that my destiny was to become a software developer.
