My job I am going to try to describe what I do at work. I am a computer engineer and my tasks are: - web based document management system redesign and development from a desktop version build in Visual Basic (a programming language). Initially, to mantain, all funtionalities, web version invoked Visual Basic DLLs via Java Native Interface (other programming language). Later, the core was built in Java (other prog. lang.). Performance is very important because of the large number of documents it has to manage. . digital signature module development which generates and validates diferents types of signatures in documents. . Aplicattion Program Interface (API) development to be used by third parties. This... and repair bugs (code erros)! Thanks!
