I spent 5 years working on software development at Opciones. There, I provided continuous development to a Ruby on Rails application that involved electronic billing services for national clients. I also worked in the migration to a new ERP based on Apache Ofbiz from an old one based on AS400, for the internal use of the company. Through my involvement in these undertakings, I learned the use of a wide array of technologies and tools for development, mainly in the subject of web development, which also included deploying and maintaining production environments, and version control, as well as development methodologies.
