Experience

  • GStreamer V4L2src Plugin (Development)
    https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-good-plugins/html/gst-plugins-good-plugins-v4l2src.html

    I authored the GStreamer v4l2src plugin. If you are using your web cam on Linux, there's a good chance you are using code written by me. I also created several fixes for GStreamer.

  • Radio Bus (Development)
    http://www.mobicity.com.br/

    I developed a virtual radio station 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 in several applications and services, one to playback, other to download and manage content, other to collect some status, and a last one to monitor the system keeping it running 24/7.

  • J1939-21/81 Library (Development)

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

  • Nokia Internet Tablet Converter (Development)
    http://www.mobile-review.com/articles/2008/inuse-n810.shtml

    This was a GUI video converter that was released by Nokia. I developed the internal converter DLL (using Direct Show and QuickTime) for Windows and Mac and also the UI hacks to minimize the number of UI requirements as possible.

    http://sweda.com.br/en/products/multifunctional-terminals/tms-3/

    This is firmware/embedded Linux programming that brings up Linux for clear and new hardware based on ATMEL AT91SAM9G45 equipped with a vast list of peripherals (DataFlash, RAM, NAND Flash, SRAM, Graphical LCD, touchscreen, smart card reader, GPRS, Ethernet, USB, UARTS, and more).

  • Billing as a PDF in a Browser (Development)

    I developed the first Hipercard system 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 a next level.
