    Software Architect

    Spain - Last active: 2 months ago - Tests: 4

    I've been working for 13 years in several of the best consulting & development firms in Spain, performing almost every possible role of my career: developer, analyst, consultant, trainer, etc. Nowadays I'm comfortable working as software architect or technical lead / project manager, however I still enjoy programming. My wide experience as a technician gives me background enough to provide the best solutions even in the most critical and tough projects. Several years as freelance developer/consultant prove my capacity of joining and getting the best results from any team, as well as my autonomy and effectiveness providing solutions for tough requirements. Right after finishing my profile here in ODesk last year I found a nice project in Cork-Ireland. After spending one year there I'm back eager to make my way in remote work. Enthusiastic with my team and projects, my commitment grows up when problems arise, especially with high responsibility roles. Sometimes, if excellence is not reachable, I believe that there always exist a clean, dignified and effective solution; extra doses of constancy and tenacity are needed in order to approach successfully any challenge.
