  Anima Educacao

  Aug 2005 - Mar 2010

  At the start of my career, I worked on academic systems for Anima, a group managing multiple private universities in Minas Gerais and São Paulo, Brazil. I began with Delphi 5, transitioning to Delphi 7 with Oracle and extensive PLSQL. Always seeking innovation, I transformed several university processes. This included overhauling student lab registration, reducing paper waste in bank statement printing, and pioneering early DevOps practices for desktop system management in 2006. These initiatives were self-motivated, reflecting my proactive and disruptive approach to problem-solving. Show less

  Algar Tecnologia

  Mar 2010 - Sept 2010

  I briefly worked for the State Department of Finance of Minas Gerais, focusing on Java EE and Oracle. Despite being new to JBoss and other enterprise Java solutions, my contributions were well-received. However, the innovative work at Maxtrack, especially their in-house development of an Android tablet, compelled me to move there. At Fiat Group Automobiles, the leading Italian car manufacturer with a strong presence in South America, I worked with C# and SQL Server. Within just three months at Fiat, my proficiency with C# was highly valued, leading to my reassignment to another project that required more assistance.

  Maxtrack

  Sept 2010 - Nov 2011

  In 2010, I developed Android applications for São Paulo's police fleet, installed on Android tablets in their vehicles. My work included vehicle tracking apps, Android system updates, and other low-level functionalities. At this early stage in Brazil's mobile development (Android was still at version 1.5), I was among the few Brazilian mobile developers. This led me to learn English and share my experiences through my personal blog (paulononaka.wordpress.com), which continues to attract thousands of visitors monthly due to its unique content, although I no longer actively update it.
