I'm software engineer working with Java, PHP and Python programming languages. I mostly work with search solutions (Solr, Elasticsearch, NLP). That is what I like most to do. Currently also responsible for DevOps in AWS for our Java application, used Cloudformation for infrastructure as a code. As a developer, I like to write clean code, I'm advocate of best practices of development, refactor code when possible to make it easier to read, test and so on.

Frelance Software Developer • January 2014 - February 2014
I worked as a freelancer software developer to Chipus IP. The goals were to allow fast and semantic search on a MySQL database with about 40 millions records and more than 10 Gigabytes of data. I also automated its database update based on a government data with information about imported electronic chips from Brazil in Microsoft Access Database format (.mdb). Used Sphinx Search to index that database and allow fastest search response time. Increased the search performance from ~6/~8 seconds (0.5 million records) to less than 1 second (40 millions records). I did that using Symfony2, PDO, Shell script, Twig, and Bootstrap.
PHP Developer • May 2009 - March 2012
Bookess is an online selfpublishing system and a social network for book readers. I started the 2.0 version of this selfpublishing system using the OOP paradigm, Scrum and other agile techniques. The challenge was to work with many data types conversion (docx, doc, rtf to pdf and swf) and serve them in an online book reader. That was a very helpful experience (the second one in my career) and I also work as a freelancer for this company nowadays. We used Subversion as version control system and a PHP5 framework developed by myself and another teammate to build the platform. That framework was based on Codeigniter. We also used Phing to automate the deployment.
