About me

Alexandre and Cinthia My name is Alexandre Devilliers, I usually go by the alias/nickname Elbereth (now you understand the name of the web site).

I am French and I consider myself a world citizen. I was born in 1979, I married in 2006 my wonderful Cinthia from Peru (a really wonderful country!). We have 2 kids: a boy and a girl.

My native language is therefore French, but I am also fluent in Spanish (lived 8 years in Madrid/ Spain, my wife is Peruvian and I currently live and work in Costa Rica!) and in English (TOEIC 910 and worked for 10 years mostly English). I also tried to learn Modern Greek (I lived in Athens/ Greece for 3 years) but with no good results... And I know the basics of Dutch.

I studied computer science, economy and management in the Université Paris-Sud XI Orsay IUP MIAGE where I got a Maitrise diploma in 2003.

Since then I worked for 10 years on SAP in the Utilities domain (IS-U module) specifically in the tariffication/billing area. I made some projects for the biggest electricity and gas companies in France, Belgium and Luxembourg.

And now I am a manager for a tourism agency in Costa Rica.
