I work as a DEV in the same office with the QA. We communicate together, the QA finds functional errors which are directly communicated to me in order to update or fix the code. Is that considered a DevOps Practice?
DevOps is the contraction of Software (Dev)lopment and IT (Op)eration(s). It's more about joining devs and those that control their environment (choice of tools, CI configurations, etc.) ideally as a single team.
QA is not part of the DevOps equation, so No
What you are describing is more akin to Agile practices, or more elementary collaboration on a task.
