About XQuadro

XQuadro is a boutique software consultancy based in Sofia, Bulgaria. We build and operate systems for demanding production environments where downtime is expensive and failures are public.
Our work includes high-availability infrastructure, integration platforms, and backend systems that process large volumes of transactions continuously (yes, including nights and weekends).
We’re small on purpose. It keeps communication tight, accountability clear, and quality high.

We aim for boring production and exciting features. In that order.
