Hi, I'm Syaifuddin 👋

Site Reliability Engineer DevOps Cloud Engineer

Introduction

I'm a Site Reliability Engineer (SRE) with 8+ years of experience in IT infrastructure. It is my duty to ensure that the IT infrastructure always remains reliable, scalable, and cost-efficient, while helping developers deploy quickly and safely. You can say it's like Oracle in Dota 2, keeping everyone alive and well.

I have been working in various roles such as Technical Support, Linux System Administrator, Network Administrator, DevOps Instructor, DevOps Engineer, and currently SRE. I have worked with various technologies such as Linux (mostly Ubuntu), AWS, GCP, Docker, Kubernetes, Ansible, Terraform, Jenkins, Prometheus, Grafana, and many more.

My mission is to learn as much as possible and as deeply as possible.
