Worked on several projects as a senior software engineer contractor. Including: development for an AI video project for use with a personal transport vehicle on an embedded Linux system, an RPC implementation for the Nvidia CUDA library, confidential computing products for OpenShift and Kubernetes, and several other cloud security projects.

• 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.

• Created embedded systems firmware for video/audio routing products using Linux, FreeRTOS, and C main() (no operating system). Firmware was written in C and primarily on ARM-based microcontrollers. Ported FreeRTOS to custom STM32-based ARM controllers.

• 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.

• Developed and maintained the company Django website, including the Python logic and templates, graphics with Inkscape and Gimp, 3D product illustrations with Blender 3D, product manuals from a template system, and an advanced product search interface.

• Built an Android app for controlling video and audio routers over a TCP/IP port.

• 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.

• Constructed all firmware, engineered most PCB hardware, and several mechanical components of a large 1024 input by 128 output composite analog video router, deployed by Los Angeles DOT to monitor traffic cameras throughout the city.

• Implemented an MRP/ERP system using Python-based Odoo (previously OpenERP) and customized for the company's manufacturing, purchasing, and sales operations.

• Developed an embedded Linux GUI for an award-winning HD Radio Exciter product, a central control daemon with custom protocol, and a Linux kernel driver interfacing with an FPGA in a Linux-based HD Radio Encoder companion product.

• 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.

• Deployed Internet and network services on Linux servers, including web, email, file sharing, and databases for this charter school, which was, at that time, the largest charter school in California.

• Implemented and maintained a Gmail email list server for organization-wide administrative communications.

• Developed interactive PHP web interfaces connected to SQL databases.

• Handled technical support calls from administration concerning Internet services.

• Developed 2D graphics routines in C for a medical patient-monitoring device.

• Optimized C graphics routines by directly accessing graphic card memory.

• Cleaned up and simplified C code written by other team members.
