About our cloud and DevOps company
OpsServing is a cloud and DevOps engineering practice working with funded startups and scale-ups across the EU and US. Seven years of production infrastructure work behind it, nine cloud certifications, and an EU legal entity in Slovakia.
Our purpose is to give a growing company the infrastructure practice it cannot yet justify hiring for: designed properly, documented as code, and handed over the moment you want it back.

// Outcomes
What the work is actually worth
Four numbers from production engagements. Client names sit under NDA, the figures do not.
- 46%
- Lower cloud spendRightsizing, Graviton, storage lifecycle and warehouse controls on a 26-service platform. A second engagement on the same platform cut another 45%.Read the case
- 50%+
- Fewer production incidentsOne alerting path, named ownership and runbooks for the failures that recur, across 26 services handling thousands of requests a minute.Read the case
- 0
- Minutes of migration downtimeA production cache moved to a managed service on a live system, using replication, a circuit breaker and a staged cutover.Read the case
- 12
- Pipelines taken off JenkinsMigrated to a managed CI with a reusable Terraform pipeline, and long-lived cloud keys replaced by short-lived OIDC credentials.Read the case
// Expertise
Where the depth is
Six areas we work in every week, each backed by production work, not a services brochure.
AWS Infrastructure & IaC
We design and migrate production infrastructure on AWS, with every resource defined in Terraform. Nothing depends on console clicks: the platform is reviewable in pull requests and ready to hand over.
6+ production migrations to AWS.
Kubernetes
We run containerized workloads on Kubernetes: cluster setup, autoscaling, workload security, and upgrades that don't take production down. Right-sizing gets the same attention as uptime, because idle capacity is silent spend.
CKA, CKAD, and CKS certified.
Cost Optimization & FinOps
We go through the bill line by line: compute sizing, storage classes, transfer waste, forgotten environments. Every finding comes with a savings estimate, so you decide with numbers instead of guesses.
AWS bills cut 46% and 45% on two engagements.
CI/CD & Release Engineering
We build pipelines that are fast, reproducible, and boring in the best way, with manual gates only where they earn their place. Deploys authenticate through OIDC instead of long-lived keys, and stop being an event your team schedules around.
More than 20 pipelines implemented or optimized across Jenkins, CircleCI, GitHub Actions, and GitLab CI.
Cloud Security & SOC 2 Prep
We harden AWS accounts to the standard auditors and enterprise buyers expect: least-privilege IAM, managed secrets with rotation, WAF and rate limiting. The evidence lives in code, not in screenshots.
AWS Security Specialty certified.
Observability & SRE
We set up monitoring and alerting that says what broke and why, before your customers tell you. Structured incident response and runbooks turn outages into a process instead of a panic.
Incidents down 50%+ across 26 production services.
// How we work
The same sequence, every engagement
No discovery phase that bills for a month before anything moves. Access is read-only until there is a written plan you have agreed to.
Assess
Read-only access first. You get a written map of what you are running, what it costs, and what would break next, before anything is touched.
Prioritise
Findings ranked by what an outage or an auditor reaches first, each with an effort estimate beside it so small items do not crowd out large ones.
Build
Changes land as Terraform and pipeline code in your repository, reviewed like any other change, proven against staging before production.
Operate or hand over
Either ongoing ownership on a monthly basis, or documentation and a walkthrough so your own team picks it up cleanly. Both are normal endings.
// Stack
What we build with
Standard tooling, in your own accounts and repositories. Nothing proprietary sits between you and your infrastructure, so ending an engagement never means a rewrite.
