Summary

I'm a systems engineer that has worked in various environments both in Australia and overseas. My experiences have allowed me to develop a strong work ethic and a passion for learning, as well the ability to adapt in difficult circumstances. I get a lot of satisfaction from delivering solutions that are not just robust and scalable, but also supportable and easy to use. Even with as much experience as I have gathered through my work, I am constantly looking for ways to learn more and improve to help deliver the highest quality output and keep my skills up to date.
