Nolan Nguyen — Backend Engineer

01.

About

I'm a backend engineer focused on backend infrastructure, currently pulled toward system design and the lower-level mechanics of engineering: how storage engines, networking, and consensus actually work.

My curiosity right now spans large-scale data systems, applied AI, and the infrastructure and DevOps work that keeps it all running smoothly. Based in Ho Chi Minh City, Vietnam.
