Hello there! I am Sunny Yiu, full stack developer in Melbourne, Australia. I specialise in web application, and applied agile and DevOps principles.

I have industrial experience and enjoy in a range of programming languages, object-oriented and functional programming paradigms, computer science, applied cryptography, security, networking, and server administration.

Although I am a fast learner and have expertise in a number of technical areas, I believe that life is a marathon, not a race. I’d enjoy to live, work, and learn at a steady pace indefinitely. Like most devs I enjoy coffee, except mine is most likely decaffeinated. 😉☕️
