• 1 - 100 Employee

• VP of Operations

  • Sep 2012 - Present

  Since 2013 I focused on maintaining Brazilian operations, adding new features to support new products. I was also responsible for generating and analyzing reports of conversion, authorization, successful billing rates, etc. I work closely with PlayPhone Brasil General manager on the definition of business strategies. I am still responsible for technical decisions and for managing all production, testing and development environments.

• Director of Engineering

  • Jan 2011 - Aug 2012

  By this time PlayPhone had already built most part of the new platform and migrated most of the territories to it. Brazilian operation was still running in the old platform and I was then responsible for adding new features to it as Brazilian market grew very fast (more than 1 million subscribers). I’ve faced performance and scalability issues as we had millions of pageviews/month and thousands of messages (SMS) were processed per minute. I was the main architect of some of biggest upgrades of the platform as asynchronous billing. I represented PlayPhone in technical meetings with the most important carriers (VIVO, TIM, Claro, Oi) and aggregators. Show less

• Software Development Manager

  • Apr 2008 - Dec 2010

  I was responsible to organize and lead dev team and QA team. My goal was to maintain and add new features to Brazilian platform and now also US platform. My direct reports were team leads, software architects and QA’s. By that time, our goal was to expand PlayPhone operations around the globe. PlayPhone decided to acquire new companies and each of them had their different technology stack. After few months it was decided to build a new platform to them migrate all operations (America., Europe, Africa, Asia, Australia) to this new platform. During this time I was responsible for developing the portal layer for all PlayPhone territories. I worked on the design of the application and then led the team during development. Show less

• Team leader

  • Apr 2007 - Apr 2008

  I joined PlayPhone to manage and lead a group of very competent developers. Our goal was to build a Brazilian version of the platform. This Brazilian version had different billing and portal. I’ve participated in the architecture definition, coded and led the developers. I worked very closely with other developers and architects in US on the definition of which technology stack we should use and also on the design of the application.
