Javier Álvarez Sedes

• I think that I am a serious and responsible person for my work, although with humour sense, able to team working, although with independence, design and creativity abilities.
• I do my work with total and deep dedication, and I ever have interest to learn more and more, and complete my knowledge, because I think I am a person with learn concerns, with 18 years old (when I wrote the first version of this CV), and nowadays, with 45 years old.
• I have linked to the Computing Sciences World from twelve years old, moment in which it was converted an authentic vocation for me, which has provided me with extensive and solid experience and knowledge in the field of Computer Science and Information Technology, with diversified skills in Systems Administration, Programming and Database Management.
• Mi Motto: "The things have to be done goodly, in other case is better not to do it". The Base of the Results are the Knowledge, the Constancy and the Illusion to reach them.
