I'm a Costa Rican freelancer working in software development and web programming. My main areas of work include Java/Oracle and .NET/SQL Server technologies (since 2000). I've also focused on PHP development since 2005. I also have expertise in related technologies, such as Struts, Spring, Hibernate, WPF, , NHibernate, PostgreSQL, etc; and some specialized technologies: Linux (Server administration and some C/C++ applications) and Delphi (with Interbase databases). My experience with web technologies, since 2005, include general PHP projects, Wordpress, Joomla, and plain XHTML websites. This includes both the basic installation and configuration of standard packages and plugins, as well as customization. I also know some Javascript and AJAX, mostly based on the jQuery framework. On database, I have experience in both the Oracle and SQL Server platforms (along with some work in PostgreSQL and MySQL), performing development work & optimization. I'm not a DBA but I'm aware of several issues that are important for that area. While I can perform simple installations, my area of expertise is not the installation or maintenance of a full blown production database server. I work from a PC, but I like both Microsoft and Linux related areas. I don't have too much experiencie in Mac software. Last, I would say I have flexibility to integrate and work on several different systems (cross-platform experience is a huge help for that), I like software architechting and have some interests and formal training in Statistics and some Data Mining.
