Some of the customers / companies I have been working for include (random order):

• Airbus Spain
• Shell
• Galp
• FirstData Iberica
• Bank Al-Bilad (Kingdom of Saudi Arabia)
• Al Rajhi Bank (Kingdom of Saudi Arabia)
• THALES Information Systems
• MATHYS International
• Sombreros Moe
• Casino.com (Mansion Group)
• PartyGaming
• Sapphire Networks

Although I am not a (good) coder at all, I had the need to create some little applications which were quite useful by the time I developed them.

Some pieces might be obsolete nowadays as newer, more feature-rich tools have hit the scene, anyway I still would like to list here some of my little contributions.

• The MLK Tools
  
• Asterix PBX Start/Stop script for SuSE
• Nagios – some small contributions in the past, like some small Makefile clean-up or how to monitor clusters with NRPE

And that is it! Not much, really, as you can see. Anyway, I had a lot of fun programming them.
