Juan Roldán

AI DevOps Engineer 📍 Rotterdam, Netherlands

Building resilient, secure and user-friendly AI services at Nebul — Europe's Sovereign AI Cloud and NVIDIA-partnered NeoCloud — powering the full stack to develop, train and deploy AI at scale.

About

I specialize in CI/CD automation, software delivery and secure access to cloud-native infrastructure — designing systems that let developers move fast without compromising security or control.

Currently, I work at Nebul, a European Sovereign AI Cloud company building the infrastructure Europe needs to own its AI future. Nebul operates Kubernetes clusters running AI workloads on NVIDIA GPU nodes and is an NVIDIA-partnered NeoCloud provider — recognized as a 2025 Gartner® Cool Vendor in AI Specialty Cloud Providers.

I collaborate with an outstanding team working toward making Nebul the backbone of European digital sovereignty — from secure, scalable delivery pipelines to zero-trust developer access across production Kubernetes environments.

Writing & Ideas

I write on my blog Backburner Thoughts about complexity, discipline and the creative process behind engineering. These writings help me reflect on how technology shapes human progress — and how engineers can keep evolving beyond the tools they use.
