I am a professional with experience in the Telecom industry in several roles. I started my career as a software developer in a telecom R&D center. Moving to a large int'l telecom company I had the opportunity to work in a number of roles, from technical support to technical sales and R&D system enginneering, working either in Brazil or US. The last few years I dedicated to frontend and backend development, especially for VoIP, and webRTC.
