What Does a DevOps Engineer Do?
A DevOps Engineer bridges development and operations by automating software delivery pipelines, managing cloud infrastructure, and ensuring system reliability. They build the tooling and processes that enable teams to deploy code faster, more reliably, and with fewer errors.
DevOps is not just a role — it's a culture and set of practices that emphasizes automation, collaboration, continuous improvement, and infrastructure as code. DevOps engineers are essential in every modern software organization, from startups to enterprises.
