Hello, my name is Feng (Michael) Sai
I build practical IT, network, and data solutions for operational teams. My background spans hands-on infrastructure support in Perth, critical-infrastructure security work in China, and data science study at UWA.
About me
Practical support across IT, networks, data, and security
I started in critical-infrastructure security and network operations, then moved into hands-on IT support in Perth while completing a Master of Data Science. I like work where the problem is real: devices need to connect, tickets need pattern-finding, and systems need clear documentation.
