Qué aporta un System Administrator a tu proyecto
A system administrator (sysadmin) implements, configures, maintains, monitors and secures existing systems: Windows and Linux servers, VMware, network, storage and identities in Active Directory, across on-prem and hybrid Microsoft 365 and Azure environments. As a freelancer, they maintain per engagement.
Their boundary: the systems technician is the support step, the systems engineer is the university variant, DevOps automates delivery. The administrator keeps what works running.

Por qué colaborar con Shakers
Ventajas de sumar este perfil con Shakers
Windows and Linux, one engagement
Windows Server and Linux RHEL run by the same person: the mixed environment stops needing two profiles.
VMware run, machines standing
VMware hypervisors reviewed, capacity watched and machines booting where they should: virtualisation does not look after itself.
Active Directory with tidy access
Accounts, permissions and groups kept clean: whoever comes in gets exactly enough, and whoever leaves is gone for good.
FortiGate perimeter, network in order
FortiGate firewall with reviewed rules and a monitored network: the traffic that should pass passes, the rest does not.
Storage and backups that restore
NetApp or Dell storage with tested backups: a backup does not exist until it has actually been restored.
Microsoft 365 and Azure as hybrid
Identities synchronised between on-prem and cloud: M365 and Azure run as one environment, without doubling the work.
Preguntas frecuentes
Si tienes cualquier otra duda, nuestro equipo te la resuelve.
Tell us about your funnelWhat does a freelance System Administrator do?
They keep the infrastructure that works running: Windows and Linux servers, VMware, Active Directory, firewall and backups, with patches, monitoring and documentation. Per engagement, no fixed seat.
System administrator or DevOps engineer?
If what is installed works and needs maintaining with support and continuity, an administrator. If the delivery cycle needs automating with CI/CD, containers and IaC, that border has its own row.
How do I choose a system administrator?
By environments told: which Windows and which Linux they ran, which VMware they held up, which restoration they backed. Certification leans on real cases and the portfolio closes the ladder.
Can a sysadmin also run the hybrid cloud?
Yes: Microsoft 365 and hybrid Azure are already territory of the craft, with synchronised identities. Cloud as a new architecture belongs to other rows.
How much does a freelance System Administrator cost?
The mechanism sets it: environment, criticality, support windows and whether it is billed by days or retainer. It is billed per engagement and the scope closes the band.
How do I check they master my Windows or Linux setup?
Ask for the inventory: which systems they ran, with which stack and which incidents they closed. Certification backs the practice and, if the specialist changes, another picks up the documentation.
What a sysadmin puts in order first
A living inventory: which servers exist, which patches they owe, which backup has truly been restored and who accesses what. After that, maintenance windows and a continuity plan.
Systems and networks, one market category
Marketplaces title the category with both words together, systems and network administrators: in the small company, firewall and switch depend on the same person.
Keeping what works
The classic engagement: Windows Server patched in its window, RHEL up to date, VMware holding the machines and NetApp or Dell storage with its backups. Modernisation arrives when the operation asks for it.
A door with its own market
The role holds categories of its own in the marketplaces and profiles with chips for VMware, Windows and FortiGate: a valued day, scarce judgement. Here the profile arrives certified and the operation stays documented.

Azure Developer
The cloud of your hybrid: M365 and Azure synchronised with your on-prem. When the engagement moves from running the hybrid to building in the cloud, their row comes in.
Database Administrator
Another discipline, another row: SQL Server, PostgreSQL and data as territory. The sysadmin prepares the ground, the engine is theirs.
Kubernetes Engineer
The delivery extreme: orchestrating containers and scaling. When the operation asks for clusters instead of servers, their row builds.
Cloud Architect
Designing the new cloud environment instead of running the installed one: when the plan precedes the maintenance, their row draws it.
