Hi, I'm Tam Nguyen — a platform and infrastructure engineer with a focus on building systems that scale.

I've spent the last 15+ years designing, automating, and securing cloud and on-premise infrastructure at companies like Microsoft, Amazon, and high-growth startups.

I specialize in solving technical problems hands-on — whether it’s reducing cloud spend, improving reliability, or automating infrastructure at scale. Along the way, I’ve also guided teams and mentored engineers, ensuring the work we do makes an impact.
