/ about
Hi, I'm Zaidan.
I'm a DevOps / Platform Engineer based in Bogor, Indonesia. I started as a full-stack web developer, which is still how I think — the platform exists to make shipping easy, so I build the tooling teams actually use, not just the infra under it.
These days my work lives where reliability, cost, and developer velocity meet: keeping production quiet, pipelines quick, and the cloud bill honest. I like the unglamorous problems — the ones that save a team an hour every day.
