I keep your servers, cloud and mailboxes running.

Aishwarya Ravikumar, System Engineer. I manage cloud, Linux, Windows, Microsoft 365 and Google Workspace environments so teams can work without thinking about the infrastructure under them.

About

I am a System Engineer who looks after the everyday systems a business depends on: servers, user accounts, email, storage, backups and access.

My approach is simple: keep things stable, document what I change, and fix the cause of a problem instead of the symptom. When something breaks, I want the team back to work fast and the same issue not to return.
