GStreamer V4L2src Plugin

https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-good-plugins/html/gst-plugins-good-plugins-v4l2src.html
The GStreamer v4l2src plugin that I authored. If you are using your webcam on Linux, there's a good chance you are using the code I wrote. I also created several fixes for GStreamer. I also ported several plugins from GStreamer 0.8 to 1.0.

Radio Bus

http://www.mobicity.com.br/
A virtual radio station I developed for Recife's public buses. The devices were installed and connected to the bus audio system to play spots and random music all day long. There were spots played on the schedule's basis and geolocation basis. It was developed in Java for Android, separated into several applications and services: one to playback, the other to download and manage content, the other to collect some status, and the last one to monitor the system, keeping it running 24/7.

J1939-21/81 Library

J1939-21 and 8 I implemented as a library from scratch. The library was initially developed for CMSIS but was designed to be very portable using hooks. The library is now running in thousands of ATMs and their related equipment. It was also ported to Linux.

Billing as a PDF in a Browser

https://www.hipercard.com.br/
The 1st Hipercard system that I developed that was capable of showing exactly to the call center support operators what the customers had printed in their hands. Before this system, operators saw the bills in an unformatted text as it was stored in the mainframe. The system improved the quality and speed of the call center operators to the next level.
