v4t — DevOps, consulting and IT infrastructure in Ljubljana, Slovenia

DevOps · Consulting · IT

We build, automate and operate the infrastructure your product runs on — then hand it back documented, monitored and boring. The good kind of boring. Usually for less than the cloud bill you are paying today.

Services

devops & automation

CI/CD pipelines that actually gate quality. GitOps delivery, reproducible builds, release automation and the scripts nobody has to remember.

  • GitLab CI / GitHub Actions / Azure DevOps / Jenkins
  • GitOps with Argo CD
  • Build, test and release pipelines

cloud & infrastructure

Infrastructure as code from the ground up, or untangled from whatever grew by hand. Migrations that land without a maintenance-window horror story — and a cloud bill we go through line by line until it makes sense.

  • Terraform / OpenTofu, Ansible
  • AWS, GCP, Azure, Hetzner, on-prem
  • Cloud cost optimisation & rightsizing
  • Cloud migration & exit planning

kubernetes & platforms

Clusters that survive contact with production. Sane defaults, real resource limits, upgrades that are a Tuesday instead of an incident.

  • Cluster design, hardening, upgrades
  • Helm, Kustomize, operators
  • Internal developer platforms

observability & sre

Know it broke before your customers tell you. Metrics, logs and traces wired into alerts that mean something, with runbooks attached.

  • Prometheus, Grafana, Loki, OpenTelemetry
  • Tracing with Jaeger & Tempo, errors with Sentry
  • SLOs, alerting, on-call runbooks
  • Incident response & postmortems

it operations & support

The unglamorous layer that keeps a company working: identity, backups, patching, networking, endpoints. Managed, documented, tested.

  • Managed servers & day-2 operations
  • Backup, restore & disaster recovery
  • Hardening, patching, access control

consulting & architecture

An outside read on your stack. Architecture reviews, audits, and fractional platform engineering for teams that aren't ready to hire yet.

  • Architecture & infrastructure review
  • Security & reliability audits
  • Team enablement and handover

Technology stack

Tools are means, not religion — these are simply the ones we run every day. Need something else? We pick it up quickly.

About v4t

v4t is a DevOps, consulting and infrastructure company. We set up your environments, look after your deploys, keep an eye on the cloud bill, and tune the whole thing until it runs quietly — and we treat your systems the way we treat our own.

We work as part of your team, not as a vendor at arm's length. No layers of account management between you and the engineer touching your servers: you get people who behave like in-house colleagues, learn your stack properly, and are still there when it matters. Every engagement leaves the same thing behind — infrastructure described in code, monitoring that pages the right person, and documentation your own team can pick up.

Short audits or long-term operations. Your cloud, our cloud, or a rack in your own building. We are comfortable in all three.
