Hi, I'm Dat Diep — a Cloud Engineer at NAB based in Ho Chi Minh City, Vietnam. I specialize in FinOps, cloud-native infrastructure, and Kubernetes.

I'm a Golden Kubestronaut — a title awarded by CNCF to engineers who complete all 11 Kubernetes certifications. I'm also tri-cloud certified across AWS (Professional & Specialty), Azure, and GCP.

At NAB, I led a FinOps engineering initiative that reduced cloud spend by $4M/year while keeping costs flat for 3 consecutive years despite onboarding 50+ new applications to the cloud.

This blog is where I share real experiences from preparing for cloud certifications — no fluff, just what actually worked. I write in both English and Vietnamese.

You can find me on LinkedIn, GitHub, or view my full certification list on Credly. My CV is at cv.datdiep.dev.
