Everaldo
Brazil
I have more than a decade of experience
with Object-Oriented Programming and
more than eight years with the Ruby
language. I had lectured on several
Computer Science courses at a number of
different universities. I prefer working on the
back-end using Ruby on Rails, but I also can
do Full-Stack using a variety of
technologies, like jQuery, ReactJS and
VueJS - my favorite library. I've been a Linux
user since 2004. Even being a vim user for
so long I'm pretty happy and open to try
VSCode. I was also a fan of MongoDB and
I'm always learning new technologies and
languages. My latest passion is the Flutter
Framework. I'm an avid reader, very
interested in Design Patterns, Testing and
Software Architecture. You can always find
me reading some manual and API docs.

Upgrading a Ruby on Rails
Application
https://www.marcatofestival.com/
As a member of the team we
upgraded a +10 years old Rails
Application.
As a remote developer, working
together with the onsite team, I've
tested the application, by
comparing the behavior and
outputs with the master branch in
order to find and fix
undocumented bugs.
I've fixed failed tests by upgrading
code and assertions to the
standards used in the current
version of the framework and
libraries.
We successfully upgraded a +10
years old Rails application,
improving security and
performance.
