Professional Experience
March 2015 – Today Ericsson R&D. Software Defined Networking (SDN). Senior Software Engineer.
 Push organization to refactoring our code. We need to run Component Test using gmock/gtest instead of Function Test (FT) using TTCN. We
were able to write more than 800 test in three weeks, covering 80% of our code. They will run in 5 seconds, previous FT version takes 8 hours.
 Different actions to improve performance of our application. We improve our Time To Response (TTR) by 15%.
 Refactoring our System Test code to improve running time in an 30%.
 My team (6 people) is declared as the best team of our design unit. We are cross-functional, very professional and very predictable.
Jan 2014 – March 2015 Ericsson R&D. Virtual Service-Aware Policy Controller (vSAPC). Senior Software Engineer.
 As active member of eSAPC Design Community (SDC), I propose techniques and ways of working to improve efficiency on design unit.
 Organizer SDC conferences E=mc2 (Ericsson Multithreaded Clean Code). It explores new features of C++11 related to multithreading.
 Design and implementation of core for Sy solution in eSAPC. It is written in C++11 and the first phase was tested using GoogleMock.
 Encourage development teams to use best techniques to solve C10k problem.
 As a member of a cross-functional team I have participated into definition and writing of functional test cases by using TTCN language.
 Technical support for evaluation and selection of new candidates
