Free Software

Ever since I first read about Free Software when I was a teenager it became clear to me that it was the ethical way of developing and using software, and that closed-source software cannot be fully trusted.


My favorite programming language for its cleanliness, readability, flexibility and ecosystem. I like learning and using other languages that are good for other use cases, such as Clojure, Haskell, Rust or Go.


I have done web development with Django since 2007. I have developed complex websites from scratch, including HTML, CSS, Javascript, server-side programming, deployment and maintenance. Nowadays I focus on the backend.


I'm interested in all aspects of computer security, including cryptography, system and application security. Security is a way of life, it must always be present, cannot be an afterthought.


Bitcoin, Ethereum, Monero, Namecoin... Cryptocurrencies are going to change the world, but same as the Internet wasn't appreciated by most people in the 80s and 90s, it will take a few years for the technology to mature and be massively adopted.


Centralization leads to abuse and censorship. Decentralized projects like OpenBazaar, IPFS and the aforementioned cryptocurrencies can be a disruptive force towards a freer world.


We don't hide our actions because they are bad or wrong, but because they are private. We have a right to privacy even if we have nothing to hide. I put a lot of effort into defending my privacy, and educating people as to why it is important.


I enjoy taking photographs and have been improving my technique ever since I got my first digital camera in 2003. Art doesn't come easy to me, photography allows me to express myself creatively.

Personal projects


Tools I use

  • Debian GNU/Linux is my trusted operating system. I used to run sid, then after some years I moved to testing, and currently I run stable+backports.
  • KDE is my preferred desktop environment. I have used GNOME 2, Unity, XFCE and xmonad in the past, but I like KDE's configurability.
  • Firefox is my browser of choice. I don't fully trust Chrome/Chromium because they send data to Google.
  • Emacs. I used Vim for 4 years, but always wondered why so many people loved Emacs. Now after 8 years using Emacs exclusively I understand.
  • Owncloud to sync my contacts, calendars, notes and files across devices.
  • Yith Library to manage my passwords.
