I've been building software professionally since 2005, working across a wide range of technologies, platforms, and teams. Over the years, I've specialized in backend development, infrastructure, and open-source systems. Below is a timeline of my experience: key roles, milestones, and the work I'm most proud of.

What I Do

I work on the OS layer beneath Kubernetes: making fleets of nodes, including GPU ones, boring, reproducible, and safe to upgrade.

Over twenty years I have moved deliberately down the stack: data infrastructure at Telefónica, backend and performance work through the web years, Linux system tooling at SUSE, and now Kairos, a CNCF Sandbox project rethinking how Linux distributions are built, upgraded, and operated at scale.

  • I am one of the maintainers of Kairos, the CNCF Sandbox immutable OS: 1.8k GitHub stars, 56 contributors, and adopters running it in production from university lab networks to Web3 hosting fleets.
  • I made Kairos run on riscv64
  • I designed how Kairos admits maintainers: an application and onboarding path backed by automated voting, so the project can grow its maintainer bench without me in the loop.

Open-Source Software

I've been immersed in open source since the early days of my career, shortly after I started using Linux. I believe it's one of the best models for building quality software, and eventually, I was able to give back by contributing as a developer. These are some of the most meaningful projects I've contributed to.
