Teo Ruiz

I'm a software engineer, I live in Madrid and work for jobandtalent as a VP of Engineering.

I generally like learning all the things.


Over the past ~12 years I've been lucky enough to work on great projects and with great people:

  • I co-maintained a Debian-based distribution (while being an official Debian maintainer)
  • I was founding member of the engineering team at FON
  • I managed the web development team at El País, one of the biggest newspapers in Spain
  • I've been CTO at Busuu, the biggest language learning startup in the world by numer of users
  • I've headed the great engineering team at Lyst in London

You can see my full CV and contact me about contracting work and new projects on LinkedIn.


In tech I like free software (free as in free speech), DevOps, systems and infrastructure engineering (especially on AWS and the Google Cloud), scalability, databases, automation, coding for fun and profit, the startup scene, and in general being geeky about technical things.

In Real Life I like music, music, music and then some other stuff (randomly sorted, ridiculously non-comprehensive list): writing, travelling, politics, quality alcoholic beverages, coffee, hanging out with my friends, food, photography, economics, reading, movies and running.

Languages and writing

Spanish is my beloved mother tongue but I have a crush for the English language so some of the posts on this old blog were written (some would say committed) in that language. Please bear with me.

Python and Ruby are my preferred languages for everything else, although I've had the doubtful pleasure of working with PHP for a few years. The Go language has recently gone to the top in my toolbox ranking and I try to use it for new projects.
