    Software for web and embedded devices. Django Arduino Twisted Asterisk

    United States - Last active: 11/20/2014 - Tests: 1 - Portfolio: 4

    I like python/twisted/django. I love making web apps. I like working with small embedded devices and computers that interface with the real world. I think programming for those devices, and making things light up, turn on, and move, is really cool. Lately I've been on a distributed apps and non relational databases fix. Distributed twisted servers, message queues (AMQP), XMPP/Bosh and Cassandra, are where I think the next cool new things are going to come out from, so I'm playing with that stuff. Professional work: • Lead server architect for the Pearson Education iLit project. (http://redefiningliteracy.com/) • Lead server architect for the Verizon/Terremark Command Center application (http://terremarkcc.com/) • Integral part of small team that developed Launchpad. A set of web applications, and mobile software to streamline the mobile application development lifecycle (http://www.launchpad.mobi) • Lead developer for the embedded portion of the SCADA Hydrohawk sensor product. Developed all the C code that ran on PIC12 and PIC16 microcontrollers to monitor sensors, and implemented the MODBUS protocol for use with legacy industrial devices. (http://www.youtube.com/watch?v=l0Z44QGY0-U) Side projects: • Arduino RFID card reader firmware and twisted python application interface. (https://github.com/juancferrer/arduino-pro-rfid) • Android application and custom arduino compatible firmware for robot control (https://github.com/juancferrer/hexabot) (http://www.youtube.com/watch?v=C8LEpY3_4Xg) • Simple python server and android application using Google Cloud Endpoints. https://github.com/juancferrer/lma • Xbee/Zigbee controlled, arduino and sheevaplug powered robot.
