Community 07 · IT infrastructure and support
Fair4Chain, IT infrastructure and support freelancers validated by their peers.
Experts who keep the information system running: availability, operations, evolution. Chosen by their peers, supported by one of them, with a 10% margin written on the quote.
The community’s profiles.
Fair4Chain brings together four roles in two families, systems and networks, and support, each entered on environments actually operated rather than on a title; data platforms belong to Fair4Data, and the two communities refer needs to each other.
Systems and networks
Systems administrator
Servers, directories, backups, monitoring and keeping everything in operational condition.
Infrastructure engineer
Designing and evolving infrastructure, on premises or in the cloud, automation.
Network engineer
Local and wide area networks, interconnections, remote access.
Support
Support and helpdesk
Handling user requests, incident follow-up, quality of service.
Data platforms, their flows and their governance belong to Fair4Data; Fair4Chain runs the infrastructure, the network and the support they rely on.
The tools our experts work with.
An infrastructure expert joining a team has to be productive on the environment already in place, not impose their own. The technologies most often used on the community’s missions:
- Linux
- Windows Server
- VMware
- Kubernetes
- Terraform
- Ansible
- Azure
- AWS
- Active Directory
- Prometheus
- Docker
- ITIL
Five situations where Fair4Chain is called in.
01
An infrastructure that is no longer looked after.
An administrator’s departure leaves servers without documentation and backups nobody has tested. A systems administrator takes over what exists, documents it and puts it back in operational condition.
02
A migration to the cloud.
Hosting to leave, applications to move, costs to hold. An infrastructure engineer scopes the target and automates deployment, without interrupting the uses in progress.
03
A support desk that can no longer absorb the load.
Requests pile up, incidents keep coming back. A helpdesk reinforcement handles the flow, qualifies the recurring causes and hands the team a readable follow-up.
04
A network or an access to rethink.
A new site, remote work, segmentation to review. A network engineer designs and deploys the architecture, then hands it over to the operations teams.
05
Business continuity to strengthen.
A recovery plan never replayed, monitoring that warns nobody. A systems administrator or an infrastructure engineer sets up monitoring, tests recovery and documents the procedure.
Joining Fair4Chain.
You enter Fair4Chain through a 30-minute meeting with its community lead, not through open registration: the lead opens access after meeting you, and across all communities one profile in three presented is retained.
- 1A 30-minute video call with the community lead. The discussion covers environments actually operated: scope, constraints, incidents met and what was fixed.
- 2The community lead validates your entry. If your background fits, they tell you during the call and ask whether you prefer a profile pre-filled from your LinkedIn page, or a CV you send. They then validate your entry: criteria reviewed with the ecosystem’s experts, references checked with previous clients.
- 3You receive an invitation to the talent space. An invitation link lets you create your password and enter. If the link has not been opened, a reminder goes out three days later.
The same price as everywhere at Fair4B.
The expert’s rate, 10% for Fair4B, 10% redistributed to the members who brought, selected and followed the mission: the three lines are written on the quote, before the first profile.
On an infrastructure or support mission, this means two concrete things. The client knows the share that goes to the expert and the share that goes to Fair4B, so they can compare two offers on a real basis. And the community lead who received the selected expert receives a share of the redistribution: the quality of selection is rewarded, not just claimed.
Questions about Fair4Chain.
How much does an IT infrastructure or support freelancer cost in France?
The daily rate is built on three variables: how rare the specialty is, experience on environments in production, and the level of responsibility on the mission. Fair4B states its margin, 10%, from the brief: the client therefore knows exactly what share goes to the expert.
What is the difference between a systems administrator and an infrastructure engineer?
A systems administrator runs and maintains the existing servers and services: availability, backups, monitoring, patches. An infrastructure engineer designs and evolves the whole, often through automation and the cloud. The first keeps what exists running, the second prepares the target.
How does Fair4B select its infrastructure and support experts?
In three steps. A 30-minute meeting with the Fair4Chain community lead, on environments actually operated. The lead then validates the entry, drawing on the ecosystem’s experts and having references checked with previous clients. Then the invitation to the talent space. This selection is one of the five roles paid through redistribution.
Fair4Chain or Fair4Data?
Fair4Chain for servers, networks, the cloud and support, that is, the infrastructure everything runs on. Fair4Data for data platforms, flows and their governance. When a need touches both, the two community leads talk to each other; you do not have to choose alone.
How quickly does Fair4B propose a shortlist of infrastructure experts?
Fair4B replies within 24h and presents its first profiles within 48h of receiving the brief. These timeframes come from the circuit: the request goes straight to the Fair4Chain community, whose members know their peers’ availability.
What is the difference between Fair4Chain and an IT services firm specialized in infrastructure?
An IT services firm charges a margin it does not disclose. Fair4B states 10% from the brief and redistributes an equivalent share to the members who made the mission possible. Selection is led by the Fair4Chain community lead, not by a sales team.
