Welcome, and thanks for stopping by.
I’m Juan A. Rubio, an experienced software engineer with a long-standing love for systems programming, open source, Linux, and developer tooling. Most of my background is in C and C++, and over the years I’ve worked across telecommunications, mobile, embedded software, and multimedia systems.
Right now I’m also exploring AI engineering, especially where it becomes practical rather than theatrical: better tools, better workflows, useful automation, and software that helps real people get things done with less friction. I still enjoy working close to the metal, but I’m equally drawn to small products and systems that solve everyday problems well.
I’ve worked through my own company, Aratelia Limited, and in the past I’ve collaborated with teams at Vodafone, Lucent Technologies, Ericsson, Symbian, Nokia, ip.access, and Videojet Technologies.
A big part of my open source history is Tizonia, a cloud music player for the Linux console and the first open source implementation of the OpenMAX IL 1.2 specification from The Khronos Group.
Outside work, life is mostly about family, trying to stay active, and keeping curious. This site is where I write about software, open source, tools, projects, and whatever feels worth preserving on the open web.
