Why D2 exists

After a decade operating production systems, from telecom data centers to multi-cluster Kubernetes and AI/GPU platforms, the same gap kept showing up. Engineering teams understood their code, and SREs understood their clusters, but nobody owned the line between them. So we built a practice around that line.

The practice is D2 Solutions: scoped quarterly engagements for platform engineering, SRE, and AI infrastructure work. We are also the delivery partner for ID Shield Protect, running the LureLab phishing simulation and Nexably compliance platforms on EU infrastructure we operate ourselves.

D2 Solutions is incorporated in Croatia as D2 Solutions d.o.o., registered with the Commercial Court of Osijek. Full statutory details on the Impressum page.

Philosophy
The best infrastructure engineers think about what happens after deploy.

The run, the failure modes, the operator sitting in front of a dashboard at 3 AM. That mindset is why we build platforms and observability the way we do, and why the systems we deliver stay legible in production.
