Built on purpose. Backed by 20+ years of experience.

Nubosas is a specialized infrastructure consultancy founded by Carlos Perelló Marín. We are dedicated to helping scaling SaaS companies escape the "Cloud Tax" and reclaim their independence through robust, sovereign architecture.

Carlos Perelló Marín

Nubosas is led by Carlos Perelló Marín, our Founder and Lead Architect. With over two decades of experience designing High-Availability systems for global enterprises, Carlos built Nubosas with a single mission: to bring Fortune 500 reliability to scaling companies without the exorbitant public cloud price tag.

We believe that companies shouldn't be trapped by arbitrary public cloud pricing or vendor lock-in. We build reproducible, high-performance Kubernetes infrastructure that puts our clients back in control.

Carlos actively shares his raw engineering perspective, bare-metal migration guides, and Sovereign Cloud insights on his personal blog. Read his latest architectural blueprints.

Free software

Our passion for Free and Open Source Software goes beyond preference; it is the foundation of true Infrastructure Sovereignty. Building with open technologies like Linux, Kubernetes, and Ceph is how we guarantee our clients never suffer from vendor lock-in.

Telecommuting

With over 20 years of experience working remotely, we’ve embraced asynchronous collaboration as a pillar of our culture, allowing us to seamlessly integrate as an extension of your engineering team, anywhere in Europe.

Inspired by the book Radical Candor, we believe happiness at work isn’t just desirable — it’s essential to maintaining enterprise-grade focus. We foster an environment rooted in absolute honesty, direct communication, and deep care for our clients' success.

Team

Nubosas operates as a highly focused boutique. We are anchored by Carlos's deep technical expertise and supported by trusted collaborators in marketing and design. This lean approach allows us to deliver high-impact engineering results without the overhead of a bloated traditional agency.
