Who we are

How we work

Every engagement starts with a clear scope. We confirm what will be done, how long it will take and what it will cost before we begin. After the work is complete, we deliver a summary of what was done and any recommendations for follow-up.

We work on your systems with access you provide, and we document everything we do.

Who we work with

HireSysAdmin is designed for:

• Businesses running their own servers or hosting infrastructure
• Companies without a dedicated sysadmin or with a team that needs extra capacity
• Hosting providers and resellers needing backend operations support
• Agencies managing client infrastructure
• Any organization dealing with an urgent server or infrastructure problem

Based in the EU, working worldwide
