Amir SajjadKhojjasteh

DevOps Engineer · Linux Systems Administrator

Four years of full-stack work — Next.js apps, Node services, exchange and educational platforms — took me one layer down: to the Linux servers, Docker, Nginx and CI/CD that everything runs on. Now I keep production boring, on purpose.

The machines everything else depends on.

Build it, ship it, proxy it — repeatably.

What stands between the internet and the machine.

Application

redis
tailwind

Four years of full-stack work; still useful every day.

Quality

playwright

lighthouse
pwa

If it isn't tested and fast, it isn't done.

AI-assisted, not AI-generated

Claude Code has been part of my daily workflow since these tools arrived — the way CI is part of shipping. I know what to hand over, and what to keep.

context engineering
The context window is a budget, like RAM on a server. I spend it on the right files, in the right order, with the least noise.
agent workflows
Agents execute well-scoped work. I write the spec, set the guardrails, and stand at the review gate.
judgment stays human
AI drafts code and prose. Architecture, security, and what reaches production are mine.
