Services
Three things we do properly.
Deep in a few areas rather than shallow across everything — and every engagement ends with your team owning the result.
Featured projects
Systems we built, and why they work that way.
Each came out of a production problem. The reasoning is documented whether or not the source is public.
Selected clients
Teams we have built for.
Airline modernisation, enterprise private cloud, and long-running infrastructure operations — in Ireland and Romania. Some engagements are delivered through partner consultancies, which we name.
Why choose us
What you are actually buying.
Production-first engineering
Health checks, metrics, failure handling and runbooks are part of the deliverable — not a second phase that never gets scheduled.
Open-source expertise
We build on open source and publish what we can. Infrastructure MCP is MIT-licensed and public.
Infrastructure specialists
We are deep in a few areas rather than shallow across everything, and we will tell you when a problem is outside them.
Automation-first mindset
If a change can be made by clicking, it will eventually be made by clicking at 3am by someone guessing.
Maintainable architectures
The measure of an engagement is whether your team can confidently change the system six months after we leave.
Common questions
Questions buyers actually ask.
Straight answers, each repeated in context on the matching service page.
Can you work with our existing models and weights?
Yes. The routing and serving layer is model-agnostic — it cares about worker health, queue depth and throughput, not about which weights are loaded. We have run this pattern across mixed fleets where each GPU serves a different model.
We already have Terraform. What changes?
Usually the state layout, module boundaries and the review path rather than the tool. Most of the pain we are asked to fix comes from a single monolithic state and modules that cannot be composed, not from Terraform itself.
Which Ethereum clients do you support?
Erigon, Geth and Reth. The routing layer detects the client automatically and accounts for capability differences, including methods that exist on only one implementation.
