About Carlos Perelló Marín
I’m a software engineer and DevOps consultant who enjoys turning complex infrastructure problems into reliable, elegant solutions. With over 20 years of experience, I’ve built software and infrastructure for startups and large enterprises across Europe and the U.S., including four years as a contractor for a Fortune 500 company.
My roots are in Python software development—from building web applications and APIs to writing automation and data-processing tools. That background still shapes the way I design solutions today, and I continue to offer Python development and integration services when projects need both strong coding and solid infrastructure.
Today I’m the founder of Nubosas, where I help startups and SaaS companies design and operate cloud, hybrid, and bare-metal Kubernetes environments. My focus is on automation, security, and cost efficiency—whether that means building a high-availability Talos cluster on bare metal or creating GitHub Actions pipelines with Terraform/OpenTofu.
Outside of client work I share technical insights and occasional reflections here on my personal blog. If you’d like to discuss a project or just connect, visit Nubosas or reach out on LinkedIn or X (Twitter).
