What I can do better!

My work.

IT Consult

With over 15 years of experience in computer networking and open source solutions can take a broad view of much of what happens in it and make use of it and fruit to meet project demands, taking them as daily challenge for achievement and learning.


My first computer book was a book of programming in BASIC for MSX and since then I have been acquiring experience in a series of programming environment at the beginning on the desktop and in the cloud today. Despite working with PHP since version 3, in recent years I have worked a lot with Python, passion language at first sight, perfect for Front-end and management *nix systems.

Linux and BSD variants

With Linux, my first experience was on Slackware 3.5 and since then I have him as a defiant passion, I followed the whole evolution of your kernel and sponsored distributions and parallel met our system "demonic" FreeBSD, through BSD variants such as OpenBSD and NetBSD but consolidating on FreeBSD and earning the nickname "gugabsd".

Network Service

In my experience with BSD/Linux, i went through various environment and in them I gained expertise in managing networked productivity tool, starting with Apache and Bind, Qmail and Postfix past, customizing proxy environments with Squid and leaving Mr. Gates with hair-raising to implement heterogeneous environments with Samba and Cia.

Open Source Community

Since the beginning, when I learned the concept of ratio in the old BBS`s, I learned to share my work and my knowledge and in that spirit I always tried to contribute my best. Whenever there was a need to learn and know the background a tool, the developers tried to always be with their updates until I have enough experience to make my own free projects.

Orchestration and Virtual Environments (DevOps)

Today, with the implementation of cloud computing and the need to distribute environments, the need arises to work with a tool to unify the management of all this and it comes tools like Puppet, Chef and Ansible - Our friend DevOp
