About

I started my career as full stack web developer for local agencies on my city. Working with PHP and javascript while learning C, I figure out that browsers need a long way to go, so I start to read about it and always wanted to help with open source community. After some years of research and learning, I start to contribute for Firefox developer tools.

One year later, I was contributing to many projects that I was involved such like KDE projects (AMOR, kde default games), creating tools like pcap2cshark and maintaining FluentPDO.

From 2012 to 2014, I was working for a local software house developing and improving the financial module for the system that manages engineers/architects registry in the country (Brazil). Here, I learnt a lot about databases and how to scale a project accessed by 106 thousand (average) of users.

From 2014 to 2016, I joined a local cardholder company, working as developer improving their financial system written in PHP, Java and PostgreSQL.

In summer 2016, I joined Evolux team as support analyst. Here, I worked automating painful telephony support tasks. After some weeks, I was allocated as Software Developer working with FreeSWITCH community to create a communication plataform over WebRTC called Verto Communicator. I observed and learnt how to work with a big communication plataform and how to improve and debug it.

When finished Verto Communicator, Evolux starts an outsourcing for SilentCircle Private Communication company to develop SPA applications. Here, I lead three developers to make beautiful and functional applications using React, Redux, webpack, es6, functional paradigm and a lot of other fancy technologies.

Currently (2018), Evolux platform is growing very fast and I am improving Evolux realtime communication backed by FreeSWITCH providing a onpremise and multi tenant plataform (configuration based), using amazing tools like rabbitmq, phoenix, python and javascript (es6).
