Point Road Solutions•  February 2020 - September 2020

In charge of most of the web app development. Backend: Python (using webserver, WebSockets, picam, ffmpeg, among others). The app is running on a Raspberry Pi (Linux OS), and it interfaces with a TI mmWave radar, IMU (i.e. accelerometers and gyroscopes), GPS, and Pi Camera. Frontend: HTML5, CSS, JQuery, Javascript, Websockets, 3D WebGL, Video streaming, among others. In The UI, the user can add/remove up to 5 servers (i.e. Raspberry Pi’s running independently its own radar), where the user can display “live and playback” radar point clouds (3D WebGL), as well as video streaming.

Software Engineer II

Xerox•  August 2013 - June 2017

Provide object-oriented design and programming, multi-threaded programming, and testing for embedded systems. Work under agile software development methodology and test-driven development, using C++ 11, Python, SQLite, JSON, ClearCase, and Visual Studio .Net and applying different Design Patterns. Highlights: • 3D Printer Project: Designed and developed the interface between MagneMotion (Conveyor System) and the printer (Continuous, Hi-Speed and 3D) to control the carts asynchronous movement in order to print correctly. It was successfully accomplished a month before the deadline. • Transportation System (TS): Restructured the GPS Navigation Subsystem into a new architecture based on components, implementing a new interface to handle the communication between different GPS chips (e.g. Ublox, Garmin and Raystar) and the subsystem. • TS: Programmed the interface to control the embedded EEPROM, and learned the IPC messages usage and socket programming. • TS: As a team member, developed part of the vehicle monitoring feature which receives messages coming from J1708, J1587 and J1939 network, standardizes them in a specific format and sends them over-the-air (OTA) to the server. TS: Created a Python script to update the SQLite database based on every subsystems’ INI file, then updated the main Software Release script to use the updated database. Converting a manual process to an automatic process with the usage of the script and saving a lot of execution time.
