    I have been a Linux enthusiast since 1995, and I've been working as a system administrator on Linux servers for the last 10 years. I am certified with a Linux Professional Institute level 2 certification. I think that the most important factor in systems administration is the ability to face new problems and to adapt to the ever-changing challenges of technology, networking and security. The true skills of a good system administrator emerge when facing a task he/she has never solved before. My working philosophy: to always prefer long-term well documented solutions to quick ad-hoc fixes; to stick to published standards as much as possible; to strive to implement solutions that are elegant as well as practical. I love documenting what I do and I will be happy to share knowledge with my employers if they so require. My main areas of expertise: - HTTP servers (Apache, Nginx) and FTP servers (proftpd) - Mail systems (Postfix + LDAP, Dovecot, Amavis, Spamassassin, SPF and DKIM managing) - Amazon Web Services (EC2, S3, Route 53, RDS) - LAMP stacks - Firewalls (Iptables, Firehol, Apache mod_security) - Integrated solutions (iRedMail, Bitnami Stacks ...) I can communicate fluently in English, Spanish, Catalan and Italian.  less
