Paulo Jerônimo ME

Paulo Jerônimo Treinamentos Eireli-ME was the name of my own micro company. It was founded in September 1999 with the name ALP Engenharia de Software Ltda. For many years my company lived only attending some specify customers, without a trademark. Therefore, in April 2010, I decided to give it one: Lado Servidor. Using this name, I developed many works involving the creation of custom training to many customers. Also, I gave solutions and did many services associated with Java application servers. Another work was the application development (especially in Java EE, on multiple platforms).

I kept the Lado Servidor’s blog. This blog is available, now, for historical reasons. It does not suffer updates anymore. All the posts created for this blog was written in Brazilian Portuguese (pt-br). Those posts contain various solutions and tutorials for some technologies, especially those addressing the use of Java EE middleware (JBoss EAP, GlassFish, IBM WebSphere, etc). Some friends (including Marcelo Ancelmo and Bruno Borges), also with extensive knowledge in the Java EE world, contributed in adding some posts to Lado Servidor blog.

In April 2014, I decided to not update Lado Servidor blog anymore. That decision was done to give more emphasis in my own name. Therefore, I asked my accountant to change the name to the current that I’m using.

Through my company, I played the following roles:

I was hired to develop commercial systems (Financial Check Poster Control, Telesales, Postal Refund, etc) using as the Pascal programming language.

My development programs were built by using with Object Oriented (OO) Pascal. OO was introduced in Pascal with Turbo Pascal 5.5. That compiler was my first compiler when I was studying Computer Science at the university.

It was at this time that I migrated my interests for object orientation in C++ and started working with this language.
