I spend most of time building
Enterprise Web Applications using Object-Oriented Analysis and Design
in Java, Eclipse and Linux, some Perl hacking too.
I started working professionally in the year 1991, primarily in IBM mainframes using CICS, CSP, VSAM, IDEAL, JCL.
In mid-1993 changed the mainframe by the visual world of client-server
at that time, especially with Sybase, Visual Basic and SQL
Eventually i was invited to participate in some Multimedia projects,
which in 1995 were entering our country. This period was very
entertaining, and also was mixed with some development and introduction
in my life of Case tools for modeling databases. After a year i hired
again to work for Banks and Financial Institutions using Mainframes and
some SCO Unix.
In early 1997 I began to support a group of designers who needed to put
database content on their pages, and so investigation lead me to Perl,
i get caught and we started to build everything for the Web in Perl and
th backoffice in Visual Basic all this with Oracle running on an old
Sun 1000E. In late 1999 I was introduced to Linux by one of my
colleagues, like many changes, “i resisted it, but it was the best I
could have done”. Currently i pass my life between developing web
solutions in Opensource platforms and as Consultant, Advisor and
Teacher in various subjects related to Objects, Java, Perl, Linux
and the Internet.
