Work Experience
首席技术官
Matrix Switch
- Developed 100% of the company software for a manufacturer of professional broadcast video and audio routing products. Engineered hardware on several products for schematic capture and PCB layout using KiCad.
- 使用Linux为视频/音频路由产品创建嵌入式系统固件, FreeRTOS, C main()(无操作系统). 固件是用C语言编写的,主要是基于arm的微控制器. 将FreeRTOS移植到自定义的基于stm32的ARM控制器.
- Engineered PCB hardware and developed VHDL logic on a Xilinx FPGA for a 48x48 digital audio router utilized in sports stadiums throughout the USA.
- Engineered hardware for video crosspoint/controller and developed embedded FreeRTOS firmware for a 64x64 SDI digital video/audio router using a dense BGA component footprint.
- 开发和维护公司Django网站, 包括Python逻辑和模板, 图形与Inkscape和Gimp, 3D产品插图与Blender 3D, 来自模板系统的产品手册, 以及先进的产品搜索界面.
- 构建了一个Android应用程序,用于通过TCP/IP端口控制视频和音频路由器.
- Developed an SDI video/audio test application with a Black Magic Decklink card and a C++ API. A test 12G-SDI video signal was generated and looped back through the device under test that was then displayed on a monitor with data error detection.
- Engineered several 3D CAD chassis components for metal fabrication for product enclosures.
- 构建所有固件, 设计了大多数PCB硬件, and several mechanical components of a large 1024 input by 128 output composite analog video router, 由洛杉矶交通部部署,用于监控整个城市的交通摄像头.
- Implemented an MRP/ERP system using Python-based Odoo (previously OpenERP) and customized for the company's manufacturing, purchasing, 以及销售操作.

- Built a serial to an ethernet bridge product on an embedded system for bridging IP networks over a long-distance serial link.
- Created embedded firmware for a USB-controlled gambling machine button interface with RGB spectrum LEDs on an ARM-based microcontroller.
- Constructed a Linux daemon for a network gateway product for collecting gambling machine statistics wirelessly over Zigbee interfaces.
- Developed an embedded systems control interface for a medical laser and defined a text-based command protocol for it.
- Built the application firmware and Linux distribution for a 2-rack unit control panel with LCD for controlling video and audio routers.
