I also develop iOS applications. Some of my past contributions have been: the beta version of GranCanariaVG (a tourist guide of Las Palmas de Gran Canaria), LotoPhone (an app to check results of Spanish lottery) and TodosConElHierro (a non-profit app to raise funds for people of El Hierro, Spain). Right now I am working on Cloquo and OWL.
From time to time I have done several system administration tasks as well, mostly mantaining Apache and MySQL servers and network services in small offices. Not really difficult tasks but enough to learn some useful stuff.
Inventiaplus (from June 2009)
Inventiaplus is a small company that offers web-based services and consultancy work. I am responsible of the system administration department and leader developer of several web and iOS projects. I also give programming advice and technical support to my coworkers.
Desarrollos Tecnológicos e-pyme (June 2007 - October 2007)
In 2002 three students at ULPGC founded Desarrollos Tecnológicos e-pyme as a spin-off project, creating web applications according to their customer's ideas. My job there involved resolving bugs of in-house applications and helping to perform several upgrades in their system infrastructure.
