work better.
I’m a Sydney-based cloud and infrastructure professional with experience spanning system operations, administration and analysis. My career has taken me from Nanjing to Sydney, supporting both cloud and on-premises environments.
I focus on the foundations that keep services running: resilient architecture, clear monitoring, sensible access controls and automation that makes everyday operations easier.
I enjoy connecting technical decisions to business needs—whether that means improving reliability, reducing infrastructure costs or documenting systems so others can support them confidently.
