From the dial-up era to AI-native infrastructure

A relentless drive to automate, streamline and constantly improve has defined my career from the very beginning, which started in the dial-up era of the late '90s, at a family-run ISP in Sydney where telecommunications and IT truly got into my blood.

Two decades on, that same instinct drives how I design and optimise ultra-low-latency, fault-tolerant network systems for high-performance, mission-critical environments. A hands-on software developer, DevOps engineer, SRE and network-automation specialist, I bring deep expertise in network protocols, high-availability Linux/Windows infrastructure and API-driven integrations.

I lead cross-functional teams to ship robust, scalable solutions that move the needle on performance, resilience and cost. Today I'm focused on standing up production-grade LLM & agent platforms with the observability and guardrails to run them safely at scale.
